Is it dangerous to drive with a faulty immobiliser module?

This typically prevents starting entirely rather than creating a driving hazard, but intermittent faults causing the engine to cut out while driving would be dangerous — have this diagnosed promptly.

Does this module need programming after replacement?

Yes, virtually always — the new module needs to be programmed to recognise the vehicle’s authorised keys.

What is the module made of?

A sealed electronic circuit board with secure authentication circuitry.

Frequently asked questions

A fault in this module can prevent it from correctly reading the key’s transponder signal, effectively treating a legitimate key as unrecognised and blocking the engine from starting.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
