A compatible key fob must be correctly paired with the vehicle before its remote or smart-key functions will work. Chicago Car Keys provides mobile key fob programming in Chicago and selected nearby communities for many remote-head keys, standalone remotes, proximity fobs, and push-to-start systems.

This service is intended for customers who already have a compatible replacement fob or need a supplied fob programmed as part of the appointment. Before scheduling, we confirm the vehicle year, make, model, key system, current working-key count, and the identifying information printed on the remote when available. Compatibility matters: two fobs that look alike may use different frequencies, transponders, or internal electronics. At the vehicle, our technician verifies the fob, follows the appropriate programming procedure, and tests the supported functions. Depending on the system, that may include lock, unlock, panic, trunk release, proximity entry, and push-to-start operation. Some vehicles require every available key to be present during programming because missing keys may be removed from memory. Programming availability depends on the vehicle security system, condition of the supplied fob, required credentials, and diagnostic communication with the vehicle.

Frequently Asked Questions

Can you program a fob that I purchased online?

Possibly. We must verify the part number, frequency, transponder type, condition, and vehicle compatibility before attempting programming.

Why does the remote work but the car will not start?

Remote buttons and the immobilizer transponder can be separate systems. A fob may need additional transponder or smart-key enrollment.

Do I need to bring every working key?

For some vehicles, yes. Certain procedures erase or rewrite stored key records, so we will tell you which keys should be present.

Can programming repair a physically damaged fob?

No. Cracked boards, missing components, water damage, or worn buttons may require fob repair or replacement before programming.

Can you program the fob at my location?

For supported vehicles, our mobile equipment allows programming and testing at the vehicle after ownership is verified.
