How mobile car key replacement works
Where the vehicle supports it, we can also remove previously lost keys from the system during an all-keys-lost job, so an old key that fell into the wrong hands can no longer start your car. Security, not just convenience, is the goal.
Everything happens at your location. There is no waiting room and no tow — just a mobile technician, the right tools, and a working key handed to you when we are done.
Not every locksmith handles every vehicle, but we work across a wide range of makes, models, and model years. We confirm your exact key type up front so we arrive with the right blank and programmer in hand.
Understanding your car key type
The right approach depends on the key. A basic transponder key, a remote head key, and a proximity smart fob are very different pieces of hardware — which is why we confirm your exact make, model, and year before quoting.
Keep proof of ownership handy. For any key replacement, especially all-keys-lost jobs, a professional locksmith will ask for documentation showing the vehicle is yours. It protects you against theft and is a sign you are dealing with a reputable pro.
The smartest move: a spare key
A fob that suddenly stops working is not always dead. Sometimes it just needs a fresh battery or a new shell; other times it needs reprogramming. We can test which it is before assuming you need a full replacement.

What car key replacement costs
Car key pricing varies more than people expect, because the key itself does. A basic transponder key, a remote head key, and a proximity smart fob are very different pieces of hardware, and programming complexity differs by vehicle too.
That is why we quote based on your specific make, model, and year rather than a generic number. Call (408) 755-3415 with those details and whether you still have a working key, and we will give you a clear, honest price.
An all-keys-lost situation typically costs more than cutting a spare, simply because it requires additional programming. It is one more reason a spare key made today is such a smart, money-saving move.
