Vehicle lock and key problems tend to happen at awkward times and places: a parking lot, the side of the road or your own driveway. Our automotive locksmiths come to the vehicle, which often avoids a tow to a dealer.
Modern keys are more than a cut blade. Many contain a transponder chip or work as a proximity fob that must be programmed to the car. Call with the year, make, model and VIN so the right blank and programming method can be checked before the technician leaves.

Lost all your car keys?
When no working key is left, a new key can often be made from the vehicle key code or by decoding a door lock, then programmed. Some vehicles need dealer-level access, and the locksmith will tell you on the phone if that applies. Have proof of ownership ready, such as registration and ID.
Our car key replacement guide explains the process in more detail.
Locked out of your car?
Avoid coat hangers and wedges, which can scratch paint, tear weatherstripping or disturb wiring in the door. If a child or pet is inside on a hot day, call 911 first. Otherwise call us with your location and vehicle details. See how locksmiths open vehicles safely.

Frequently asked questions
Can you make a car key without the original?
In many cases a key can be made from the vehicle key code or by decoding a lock, then programmed. Some models need dealer access, which the locksmith can check when you call with the VIN.
Do you program transponder keys and fobs?
Yes. Many transponder keys and remote fobs can be cut and programmed on site. Share the year, make and model when you call so compatibility can be confirmed.
What if my key fob stopped working?
Try a new battery first. If the fob still fails, it may need reprogramming or replacement, which a mobile locksmith can handle for many vehicles.
Is it safe to open my car myself?
Coat hangers and wedges can scratch paint, tear weatherstripping or disturb airbag and window wiring. A locksmith uses tools designed for vehicle entry.
Can you cut a key from a code?
Often, yes. Many car, mailbox and cabinet locks carry a code that lets a locksmith cut a matching key without the original.
