When the car stops recognizing its key
Car Immobilizer Repair
Car not starting, a key symbol appearing on the dashboard, or the vehicle suddenly not recognizing the key? The problem may be with the key, reader antenna, wiring or a control unit. We first find out what is preventing the engine from starting, then discuss a suitable repair. Proof of ownership is needed for work on the vehicle security system.

Find out why the car will not start
We check whether the car recognizes the key and whether the starting system has stored faults. We inspect the power supply, antenna, wiring and communication between units. Not every starting fault is caused by the immobilizer.

Identify the system and verify ownership
We check which security system the car uses and what repair procedures are supported. Before key programming or other protected operations, we confirm ownership or authorization.

Carry out the agreed work
Depending on the cause, the car may need a connection repaired, a key added, modules matched or a replacement control unit programmed. We explain and agree the required work first.
Show example
Car does not recognize the key
We check the key, antenna and communication with the starting system.
You need a spare key
We add keys on supported models after checking proof of ownership.
Car will not start after unit replacement
We check whether the replacement needs to be matched with the starting system.
Restore factory security settings
We assess settings after repairs and check that the original security system works correctly.

Check that the car starts afterward
We verify recognition of the available keys and that the car allows the engine to start. We also check warning messages and connected systems.

Find the cause of a no-start problem
We check whether the key is recognized and rule out power and wiring issues.
Identify the vehicle security system
We check what system the model uses and which repairs are supported.
Add a spare key
We program additional keys where supported, after checking ownership documents.
Restore communication between units
After repair or replacement, some modules need to be matched to each other.
Repair or set up electronic modules
We assess repair, programming and specialist service operations. Changes to security functions are considered only where permitted.
Check factory security settings
We check that the original security system operates correctly after repair.
Confirm proof of ownership
For key and security operations, we ask for vehicle documents or authorization from the owner.
Test the result
After work, we check key recognition, engine starting and any warning messages.
The key may not be the problem
A poor connection, power supply fault or another module can cause similar symptoms.
Different cars use different systems
Key programming and repairs vary by model, year and equipment.
Not all data can be recovered
When a control unit is badly damaged, some information may no longer be accessible.
Replacement may require additional setup
Some control units must be matched to others before the car will start.
Vehicle documentation is required
We check ownership or proper authorization before protected operations.
Checks are needed after repair
We check starting, key recognition and warning messages—not just whether programming completed.
// We investigate first, then agree the work and cost. Protected operations require ownership verification.
