What This Service Includes
Permanent removal or bypass of the stock immobiliser system
Configuration adjustments to allow ECU and module compatibility without key programming
Full bench testing to ensure engine starts and all critical systems function properly
Return of the bypassed module ready to fit — plug-and-play installation
Fixed-price service with clear scope and no hidden extras
When This Service Is Useful
This bypass is suitable in cases such as:
Lost or stolen keys, with no possibility of replacement keys or coding
Swapping a used ECU or module without immobiliser data
Immobiliser system faults that cannot be resolved reliably
Salvage or donor car parts installation where original immobiliser data is unavailable
If your module or ECU is damaged, corrupted or beyond repair, bypass may be the only viable option.

3. We perform the bypass procedure
We disable the immobiliser lock, adjust configuration as needed, and bench-test the module to confirm proper operation without factory immobiliser dependency.
4. We return your module
Receive the module back ready for fitment — no programming or dealer visits required. Vehicle should start and run once installed.

Important Information & Limitations
This service bypasses the factory immobiliser — it is not a “repair.” Immobiliser-dependent security features will be disabled.
Bypass may affect resale value, warranty or vehicle compliance. Be sure you understand the implications before opting in.
We do not supply keys, replacement ECUs or modules — you must supply the unit to be bypassed.
If the module is badly damaged or corrupted, bypass may not be feasible; in such cases we will contact you before proceeding.
Please package and label your module carefully before shipping to avoid transit damage.
