Immobilizer and security-module programming.

Immobilizer-related services

• ECU and immobilizer synchronization when supported
• Replacement security-module setup
• BCM and starting-authorization diagnostics
• Steering-lock and selector authorization testing
• All-keys-lost system evaluation on supported vehicles
• Used-module compatibility review
• No-crank and no-start signal diagnosis
• CAN communication, power and ground testing

A security code does not always mean a bad module

Battery voltage, damaged wiring, missing communication and incorrect replacement parts can prevent authorization. We inspect the complete starting chain before recommending module replacement or synchronization.

For an engine-computer replacement, review ECU, ECM and PCM programming and ECU cloning in Houston. The appropriate method depends on the original module, replacement compatibility and supported vehicle procedures.

How to arrange service in Houston

1. Send your vehicle details, symptoms, fault codes and original and replacement module labels.
2. We confirm the supported procedure and whether it requires mobile service, a shop appointment or bench work.
3. We confirm the quote and expected turnaround for your job before scheduling. Diagnosis and programming are separate services when both are needed.

Security and ownership requirements

Valid ownership information may be required. Text the VIN, year, make and model, scan codes, symptoms and module-label photos. We only perform lawful programming and security work on supported vehicles.
