Common Symptoms
- Alarm going off randomly or not arming
- Engine cranks but won't start — immobilizer preventing start
- Security light flashing — vehicle may not start
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Faulty security module — most common cause, test before replacing
- Damaged or corroded wiring/connector in the vehicle security/anti-theft system circuit
- Blown fuse or faulty relay for the vehicle security/anti-theft system
- Poor ground connection — check and clean all related ground points
- Control module fault — rare but possible, only consider after ruling out simpler causes
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($8-105 at shop, free at auto parts store for basic scan)
- Visually inspect the vehicle security/anti-theft system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $122 diagnostic fee at shop)
- If the engine cranks but won't start, check the security/immobilizer light — if flashing, try a different key. Key programming may be needed ($135-494 at dealer or locksmith)
- Replace security module if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($100-800)
- Check and replace any blown fuses in the vehicle security/anti-theft system fuse circuit — if fuse blows again, there's still a short that needs to be found ($1-19 for fuses)
