Lost Car Keys in Southlake, TX
All-keys-lost situations require immobilizer-level reprogramming — not just a new key cut. We handle the full process on-site.
Why All-Keys-Lost Is Different
When you lose every key to your vehicle, it's not as simple as cutting a new one. The vehicle's immobilizer system must be reset and a new key must be authorized at the module level. This requires direct communication with the car's security modules — FEM, CAS, EIS, BCM, or ECU depending on the make.
Most locksmiths can add a key when you already have one. Very few can handle all-keys-lost situations because they lack the diagnostic tools and programming knowledge to perform immobilizer resets.
Our Process
Verify Ownership
We confirm vehicle ownership through registration and ID before any programming work begins.
Read Immobilizer
Connect to the vehicle's security module to read the current immobilizer state and key slot data.
Reset & Program
Perform immobilizer reset (if needed) and program a new transponder or proximity key to the vehicle.
Test & Deliver
Full system verification — start, lock/unlock, proximity detection, and backup key programming.
