Can you replace a Mercedes-Benz key if I lost all my keys?

Yes. Even if you have zero keys left, we can cut and program a brand-new Mercedes-Benz key on-site. We need your VIN (on the dashboard or door frame) and proof of ownership — your registration or title works.

Can you program a Mercedes GLE key fob?

Absolutely. We program key fobs and smart keys for the C-Class, E-Class, GLE, GLC, S-Class, A-Class, Sprinter, and GLB. We come to your location — no tow to the dealership needed.

Mercedes C-Class KEYLESS-GO fob not detected — what’s wrong?

Mercedes KEYLESS-GO fobs often lose sync after a battery replacement or if the vehicle battery dies. We carry Mercedes-specific programming equipment and can reprogram on-site for C-Class, E-Class, GLE, and all other Mercedes models. Call us and we can help diagnose over the phone before you pay anything.

Is a locksmith cheaper than the Mercedes-Benz dealership for key replacement?

Almost always, yes. Dealerships charge premium rates and often require appointments days out. We come to you across Philadelphia, work on-site, and give you a free phone estimate before any work begins.

Do you come to my location or do I need to bring the car somewhere?

We come to you — home, office, parking lot, or roadside anywhere in Philadelphia and Greater Philadelphia. Our mobile technicians carry all the programming equipment on the truck.
