How to remote start a Buick Enclave for Oklahoma City drivers

To remote start a Buick Enclave with the key fob, press Lock, then press and hold the remote start button (the circular arrow) until the lights flash and the engine starts. You can also start it from the myBuick app on your phone.

The owner’s manual sets limits on how long remote start runs and where it may be used, so check those limits before you rely on it.

Keep reading below, then schedule a test drive in Oklahoma City. Bringing your own numbers to the lot settles this faster than any spec sheet.

Where is it safe to remote start your Buick Enclave?

No, not in an attached garage. The CDC says never run your car or truck inside a garage that is attached to a house, even with the garage door open (CDC, 2026). The EPA adds that carbon monoxide can build up to deadly levels in a garage even with the door open, so a vehicle should never idle there (EPA, 2025).

The manual’s remote start steps, in its order, are:

1. Press @ twice on the remote key. The turn signal lights will flash to confirm the request has been received. The parking lights stay on while the engine runs.

2. The engine shuts off after 15 minutes, or after the rest of the 30-minute total running time is used, unless you stop remote start or turn the vehicle on first.

3. After you enter the vehicle during a remote start, press the brake and ENGINE START/STOP with the remote key in the vehicle to drive it.

The manual also warns that some local laws restrict remote starters and may require the person using remote start to have the vehicle in view, so check your local rules. Do not use remote start when the vehicle is low on fuel, because the vehicle may run out of fuel.

What should you check when your Buick Enclave won’t remote start?

Start with the conditions that stop remote start from working. The owner’s manual says remote start will not work if any one of the following is true.

• The ignition is in any mode other than off.
• A remote key is in the vehicle.
• The hood is not closed.
• The hazard warning flashers are on.
• There is an emission control system malfunction.
• The engine coolant temperature is too high.
• The oil pressure is low.
• The 30 minutes of engine run time have been used.
• The vehicle is not in P (Park).

According to General Motors’ 2026 Buick Enclave owner’s manual, the troubleshooting steps are:

1. Press the start button (@) on the remote key twice from outside the vehicle.

2. The engine shuts off after 15 minutes, or after the remainder of the 30-minute total run time is used, unless you stop remote start or turn the vehicle on before the engine run has completed.

3. Remote start can be used for up to 30 minutes of total engine run time. After two remote starts of 15 minutes, or several shorter starts totaling 30 minutes, the vehicle must be started normally before remote start can be used again.

5. To cancel a remote start, do any of the following:

• Press @. The parking lights turn off.
• Turn on the hazard warning flashers.
• Turn the vehicle on and then back off.
