The system
What kind of key does your Enclave take?
Buick introduced the Enclave for the 2008 model year as a large, comfortable crossover with three rows of seats, and it has gone through more than one full redesign since. For key purposes, the most important dividing line falls between the first generation, which ran for about a decade, and the redesigned Enclave that followed. The earlier vehicle is built around a cut key that turns a traditional ignition. The redesigned vehicle is built around a proximity fob and a start button. Knowing which side of that line your Enclave sits on tells us most of what we need.
First generation Enclaves generally use a cut key with a transponder chip inside the head. The blade turns the ignition cylinder in the steering column, and the ignition reads the chip before allowing the engine to run. Most of these vehicles pair that key with a separate remote fob for locking, unlocking, the power liftgate and, on equipped vehicles, remote start. Owners often keep the key and the remote on the same ring and think of them as one thing, but they are two separate credentials that are replaced separately.
The redesigned Enclave uses a proximity fob. The fob stays in a pocket or purse, the doors unlock when a handle is touched on equipped vehicles, and the engine starts with a button on the dash. The fob contains a hidden emergency blade for the driver door. On vehicles equipped with remote start and a power liftgate, those functions are built into the fob buttons as well, which makes a single fob responsible for a lot of daily convenience.
The newest Enclave continues with a proximity fob and adds more electronics around it. Newer General Motors vehicles can require an online authorization step before a key is added, and some all keys lost situations on the newest platforms are more involved than on older ones. We identify the exact vehicle before quoting, because the answer for a first generation Enclave and the answer for a current one are not the same.
Systems by generation
A key in the column, then a fob in the pocket
The table below summarizes what we most often find on each Enclave generation. Individual vehicles can differ because of trim, options, dealer replacements and prior repairs, so we confirm at the vehicle.
| Generation | Typical key | Ignition | What the job usually involves |
|---|---|---|---|
| First generation, 2008 through 2017 | Cut transponder key, usually with a separate remote fob | Key turns a cylinder in the column | Cut the blade, add the chip to the vehicle, and program the remote separately if it was lost too |
| Redesigned Enclave, 2018 onward | Proximity fob with hidden emergency blade | Push button start | Program the fob, cut the emergency blade, test remote start and liftgate buttons where equipped |
| Newest Enclave | Proximity fob | Push button start | Identify the exact platform and security requirements, then program and test |
| Any generation, all keys lost | Nothing to copy | Varies | Originate a blade from the lock or a key code and register a new key without a working donor |
On a first generation Enclave with a working key in hand, adding another key is usually one of the simpler jobs we do. Some older General Motors vehicles can learn an added key using existing working keys, while others require a timed relearn procedure that takes a set amount of time with the ignition on. Which one applies depends on the exact vehicle, and we handle it either way. When every key is gone, the job becomes an all keys lost appointment and the blade must be originated before any programming begins.
First generation remote fobs are a separate part. If you still have the key but lost the remote, the vehicle will start and drive but the doors and liftgate must be operated by hand and remote start will not work. That situation is not urgent, but it is annoying on a large crossover with a heavy liftgate, and a new remote can be programmed at the vehicle.
On the redesigned Enclave, losing the fob means losing everything at once: entry, starting, liftgate and remote start. That is why we encourage every household with a single fob to add a second one. A two fob Enclave is a vehicle that survives a lost fob with a phone call. A one fob Enclave is a vehicle that sits in a parking lot until someone comes to it.
Remote start and the second fob
Remote start is a common feature on Enclaves in Delaware, and owners use it heavily on cold January mornings in Kent County and on hot August afternoons in Wilmington. Remote start is a function of the fob buttons, so a replacement fob must be the correct type for the vehicle's equipment to carry those buttons and have them work. A fob with the right shape and the wrong button layout may start the engine with the button on the dash but never start it remotely. We match the fob to the equipment, and we test remote start before we leave.
The liftgate and the kick sensor
Many Enclaves have a power liftgate, and some have a sensor under the rear bumper that opens the liftgate with a foot motion when the fob is nearby. That sensor relies on the fob being recognized. If the liftgate stopped responding to your foot at the same time the fob started acting up, the fob is a good first suspect. If the fob works for everything else, the sensor or the liftgate may need attention instead.
Two routes
Locksmith or dealer for an Enclave key?
A Buick dealer can provide an Enclave key, and for certain vehicle faults it is the right place to go. The practical problem is that a vehicle with no working key cannot be driven there. A large three row crossover needs a proper tow, and the family schedule that depends on it stops while it waits in the service lane.
We come to the Enclave. Whether it is in a driveway in Greenville, a school pickup line in Middletown or a medical center lot in Dover, we cut the blade in our service vehicle and program the key from the driver seat. The vehicle stays where it is, and the family gets it back at the end of the appointment.
The dealer is the better choice for a vehicle with a body or security module that was replaced and never set up, for an open recall that affects the security or electrical systems, and for any case where no key works including ones that worked the day before. Those point to vehicle faults rather than a missing key, and we check for them before programming.
We use original or quality aftermarket keys and fobs, and we say which one before the work starts. On an Enclave with remote start and a power liftgate, we lean toward fobs that carry exactly the right buttons and electronics, since a cheaper fob that leaves out a function the family uses every day is not a bargain.
If the Enclave is leased, the leasing company appears on the title. That does not stop us from making a key, but we still need the registration and a matching photo ID showing you are entitled to drive it.
Diagnosis
What goes wrong with Enclave keys
On first generation Enclaves, a key that turns in the ignition but will not start the engine, with a security message or light on the dash, usually means the ignition did not read the chip. Try another key. If the second key starts the vehicle, the first key has a damaged chip. If neither starts it, the problem is more likely the vehicle.
First generation ignition cylinders can wear. A key that turns only after wiggling, or that sticks in the run position, may be riding on worn internal parts. A new key will not cure a worn cylinder, and forcing a new key into a failing ignition can make the problem worse.
On the redesigned Enclave, a message that no key was detected usually starts with a weak fob battery. The owner manual describes a backup location, usually a pocket or a marked spot, where the fob can be placed so the vehicle reads it even with a weak battery. If that works, replace the battery before doing anything else.
Fobs that ride in purses and diaper bags pick up surprising damage. Crushed buttons, cracked cases and water from a leaking bottle are all regular causes. A fob with a cracked case can sometimes be moved to a new shell if the board is healthy.
Vehicle voltage matters on a large crossover with many electrical accessories. An Enclave that has been parked for a week with a phone charger or dash camera plugged in may not recognize a fob until the battery is charged. We test voltage before programming.
Finally, family vehicles collect keys. We often meet owners who have four or five keys and fobs in a drawer and are not sure which ones still work or still belong to the vehicle. We can test them at the same visit and tell you which are active, which are dead and which belong to some other car entirely.

Where Enclaves are parked in New Castle and Kent
The Enclave is a family vehicle, and it shows up where families spend their time. In New Castle County we see it in neighborhoods in Pike Creek, Hockessin, Greenville and Middletown, at youth sports fields, outside churches on Sunday, and in the parking areas of the big shopping centers in Christiana. In Kent County we meet Enclaves in Dover, Camden, Smyrna and Magnolia, at medical offices, school events and the homes of grandparents who drive the grandchildren around. A fob goes missing on a soccer sideline, in a stroller basket, in a grandchild's backpack or in a coat that got handed to someone else. When you call, tell us where the vehicle is and whether it is blocking anyone, and whether children or pets are inside, because that changes how we prioritize the call.
Family keys
Keeping track of Enclave keys in a busy household
A three row crossover is often driven by more than one person. A parent drives it during the week, a teenager borrows it on the weekend, and a grandparent takes it for school pickup twice a month. Every driver tends to end up with a key, and over a few years nobody remembers how many exist or who has which one.
A key count is worth doing once. Collect every key and fob in the house, and ask anyone who drives the Enclave to bring theirs. Test each one. Keep the working ones, retire the ones that are dead, and note which ones belong to other vehicles. If a key is missing and cannot be accounted for, consider having it removed from the vehicle memory during the next appointment.
New teen drivers deserve a specific conversation. A teen who loses a fob at a party or a game is not unusual, and the family should know what to do before it happens. Keep a spare somewhere the teen can reach by calling home, not in the vehicle. If the spare lives in the vehicle, the lost fob problem becomes a stolen vehicle problem.
When a household changes, for example when a grown child moves out or a caregiver stops driving for the family, the key count should change with it. Getting a key back is the easy step. Removing a key that did not come back is the step people forget, and it only takes a few minutes during a scheduled visit.
Before service
What to have ready for an Enclave key
These details help us bring the right hardware the first time.
The model year, and whether the vehicle starts with a key turned in the column or a push button on the dash.
How many working keys or fobs you still have, including any at another house or with another driver.
Whether the vehicle has remote start and a power liftgate, so the replacement fob carries the right buttons.
The registration or title with a matching photo ID. If the Enclave is registered to a spouse or parent, we need to see the connection, and a phone call to the registered owner usually settles it.
Where the vehicle is parked, and whether we can reach the driver door with room to open it.
Any keys or fobs in the house that you are not sure about. We can test them at the same visit.
Straight answers
Buick Enclave key replacement FAQ
Can you make an Enclave key if we lost every key and fob?
In most cases, yes. After confirming ownership, we open the vehicle without damage, originate a blade from the door lock or a documented key code, and register a new key or fob. Newer General Motors platforms may require an online authorization step and can be more involved when no key exists. We identify the exact vehicle before quoting, and we test starting, remote functions and the door blade before we finish.
Our first generation Enclave starts but the remote is gone. Can you replace just the remote?
Yes. On first generation Enclaves the remote is usually separate from the ignition key, so a new remote can be programmed to lock, unlock, operate the liftgate and run remote start where equipped. The ignition key stays the same. It is a simpler job than replacing the key, and it restores the conveniences the family uses every day.
Why does our replacement fob not start the Enclave remotely?
The fob probably does not match the vehicle equipment. Remote start requires a fob with the correct button layout and electronics for that vehicle, and a fob with the right shape can still lack the right internals. We match the fob to the equipment and test remote start before we leave. If you bought a fob online, send us photographs before the appointment.
Can a cracked Enclave fob be fixed instead of replaced?
Often, if the circuit board inside is healthy and the buttons still work. The board can be moved into a new shell and the emergency blade cut to match. If the fob has been wet, if buttons are intermittent, or if parts are missing, a new fob is more reliable. Bring every piece of the broken fob, including the battery and any small parts that fell out.
Should we remove a lost Enclave fob from the vehicle?
If the fob could be connected to the vehicle by whoever finds it, removing it is a sensible step. Bring every key and fob you want to keep, because the process may require them all to be present. Removing a fob electronically does not change the door lock, so the emergency blade on the lost fob could still open the driver door.
Is it worth adding a second fob if we have one that works?
For almost every family, yes. Adding a fob while one still works is a shorter and simpler appointment than an all keys lost visit, and it means a lost fob becomes an inconvenience rather than a stranded vehicle. Keep the spare at home, not inside the Enclave.
When does an Enclave need the dealer?
Choose the dealer when no key works including keys that worked before, when a body or security module has been replaced and not set up, when a recall affects the security or electrical systems, or when you want original branded hardware ordered through the factory. Outside of those cases, most Enclave key work can be completed at the vehicle.
