Choose your car make in Los Altos
Modern vehicles use everything from transponder chip keys to push-to-start proximity smart fobs, and each requires the right blank plus programming to your car's system. We handle them all across Los Altos.
The advantage of a mobile automotive locksmith is simple: your car does not have to move. We come to wherever it is parked, complete the key on location, and confirm every function before we leave.
We measure success not by a single visit but by whether you would call us again and recommend us to a neighbor in Los Altos. That long view keeps us honest about pricing, thorough in our work, and respectful of your time and property.

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.
We start by confirming the exact vehicle and key technology, because the right approach for one model year can be wrong for another. From there we cut the key, program it to the vehicle's system, and verify start, lock, unlock, and remote functions.
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.
The single best thing you can do to avoid a stressful, expensive day later is to make a spare while you still have a working key. All-keys-lost programming takes more time and costs more than simply cutting a spare — a small step now that saves a lot later.
The smartest move: a spare key
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.
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
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.
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.
