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 nearby Cook County suburbs for many remote-head keys, standalone remotes, proximity fobs, and push-to-start systems.
If the vehicle also has an aftermarket alarm, our KARR and SWDS alarm guide covers that separate system.

How Mobile Key Fob Programming Works
- Confirm the vehicle and ownership. Share the year, make, model, key system, current number of working keys, service location, and VIN when requested. Proof of ownership is required before programming begins.
- Verify fob compatibility. We check the part number, frequency, transponder type, condition, and internal electronics when that information is available. Two fobs that look alike may not be interchangeable.
- Program the supported fob. At the vehicle, the technician follows the appropriate enrollment procedure. Some systems require every available key or fob to be present because missing keys may be removed from vehicle memory.
- Test the applicable functions. We test supported features such as lock, unlock, panic, trunk release, proximity entry, and push-to-start operation before completing service.
Factors That Affect Programming Availability and Quote
Availability and price depend on the vehicle year, make and model, security system, number of working keys, whether you supply the fob, the fob’s condition and compatibility, required credentials, and diagnostic communication with the vehicle. We verify these details before quoting or attempting programming.

Real Smart-Key Programming: 2018 Chevrolet Malibu in Burbank
A Burbank customer lost the smart keys to a 2018 Chevrolet Malibu. Chicago Car Keys programmed two new smart keys for the vehicle. See the Burbank Malibu job and original photo of both replacement keys.
This completed job illustrates an all-keys-lost programming request. Compatibility for another Chevrolet, model year or security system must be confirmed separately; the same procedure does not apply to every vehicle.
Before Buying a Fob Online
Contact us with your vehicle year, make and model, the seller listing, the fob part number or FCC ID when available, and whether the fob is new or used. Tell us how many working keys you have. Matching the case or button layout is not enough to confirm compatibility, and some previously programmed fobs cannot be reused.
If every key is missing, start with our lost car key replacement service. If you need replacement hardware as well as programming, see key fob replacement.
Frequently Asked Questions
Can you program two replacement smart keys after all keys are lost?
For supported vehicles, this may be possible. We programmed two new smart keys for the documented 2018 Chevrolet Malibu job in Burbank. Ask about a second key when requesting a quote so we can confirm the correct parts, vehicle support and programming requirements.
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.
