FAQ

Good questions, clear answers.

Need an answer for your specific vehicle? Call our team.

Can you add a spare car key if I still have one working key?

Yes, for many supported vehicles. We can cut and program an additional transponder key, remote, or smart key after confirming the vehicle and compatible hardware.

Can a locksmith make a car key without the original?

Yes. In many cases, a professional automotive locksmith can generate and program a replacement key using your vehicle information and proof of ownership.

How much does car key replacement cost?

Pricing depends on the vehicle year, make, model and key type. Contact us with those details for a clear quote before service begins.

How long does programming take?

Many key programming appointments can be completed during a single mobile visit. Timing varies by vehicle and key system.

Do you provide mobile service?

Yes. We travel to homes, workplaces, parking lots and roadside locations across our Los Angeles, Orange County and selected Inland Empire service area.
