Frequently Asked Questions
My dash says "No Key Detected" — what does that mean?
The car's receiver cannot hear the fob. In rough order of likelihood: a dead fob battery, a fob that lost its pairing after a dead vehicle battery, a failing low-frequency antenna, or a faulting immobilizer/body control module. We test in that order at your location, so you pay for the actual fix rather than a parts cannon.
Can a locksmith really program car computers?
For the key-security side, yes. Immobilizer enrollment, BCM key data, and theft-deterrent relearn procedures on Ford, GM, Chrysler/Dodge/Jeep/RAM, Toyota, Honda, and Nissan platforms are core automotive locksmith work in 2026, done with the same diagnostic class of equipment dealers use. Engine tuning and non-security module flashing are not what we do.
How much does immobilizer or module programming cost in Arlington?
Diagnosis plus a straightforward relearn or resync typically runs $120-$250. Module key-data programming after a BCM or immobilizer replacement runs $250-$600 depending on the platform, per typical 2026 DFW pricing. Complex European module work is assessed case by case, and we say so upfront when the dealer is the smarter route.
My security light is flashing and the car won't start. Is it the key?
Often, but not always — the same symptom comes from a worn key chip, a failed antenna ring around the ignition, or a module fault. Because we test the whole chain (key, antenna, module) at the car, you avoid the classic trap of buying a new fob that does not solve a module problem.
