What We Do When Keyless Remote Battery Is Low

When the battery of a keyless remote is low, there are a few steps you can take:

Replace the battery: The first and most common solution is to replace the battery in the keyless remote. Keyless remotes typically use small coin or button cell batteries, such as CR2032. Consult the owner's manual or check online resources for your specific vehicle model to find the correct battery type and instructions for replacing it.

The exact procedure varies depending on the make and model of the vehicle. Typically, it involves pressing a series of buttons or using specific sequences with the keyless remote or the vehicle's ignition. Consult the owner's manual or contact the manufacturer or dealership for instructions specific to your vehicle.

Replace the keyless remote: If the battery replacement doesn't resolve the issue and alternative methods are not available or feasible, you may need to replace the keyless remote altogether. Contact the vehicle manufacturer or an authorized dealership to obtain a new remote. They will be able to provide you with the correct remote and may need to program it to your vehicle.
