Mobile Car Key & Key Fob Programming
What is mobile car key and key fob programming?
Mobile key programming is when a technician comes to your vehicle and pairs a smart key, key fob, or transponder key to its immobilizer system so it starts and locks the car. MR RESCUE programs keys and fobs for many supported light-duty vehicles across southeastern Pennsylvania and nearby New Jersey. Programming only starts at $100, and key plus programming starts at $200. Vehicle compatibility is verified before dispatch.
A dealer visit means a wait and a bill. We come directly to the vehicle — at home, at work, at a hotel, or in a parking garage — confirm compatibility first, then program your key or fob on site. Many vehicles supported; select makes and models.
You're not stranded — a real person answers, confirms the price, and tells you an honest arrival window before anyone is dispatched.

Programming only starts at $100 when you already have a compatible key or fob. Key plus programming starts at $200 ($100 programming/service plus a key or fob starting at $100) — actual key and fob prices vary by vehicle.

Have a key vs. lost every key
I still have a working key
Adding another key is supported on many vehicles and is generally easier to verify.
Check my vehicleI lost every key
When no working key remains, the vehicle may require a different programming procedure, additional equipment, or security authorization. All Keys Lost availability is much more vehicle-specific.
Check AKL eligibilityProof of ownership required
Proof of ownership required. Valid photo identification and proof of vehicle ownership or authorization are required before key programming is performed.
What this service does not include
Programming and mechanical key cutting are separate services — we do not advertise on-site key cutting. We do not open safes, homes, or commercial property. Programming coverage is limited to supported light-duty passenger vehicles; some models require dealer-only programming and we say so before dispatch. We do not program keys for motorcycles, RVs, motorhomes, buses, or semi trucks.
Locked out instead? That's a different service
If your key is inside the vehicle and the doors are locked, you need non-damaging lockout entry — starting at $100. Key programming is for when the key or fob itself needs to be paired to your car.
Where we program keys
Mobile key and fob programming is available throughout Chester County (Coatesville, Downingtown, West Chester, Malvern, Exton), Delaware County, Montgomery County (King of Prussia, Norristown, Conshohocken), and Philadelphia — including hotel and parking-garage service near Philadelphia International Airport, where stranded travelers most often need a replacement fob programmed on the spot.
Extended and New Jersey coverage is quoted case by case. Check your vehicle first, then call MR RESCUE.
