Amber — check soon

Immobiliser: key not recognised

The car does not recognise the key. The engine either will not start at all, or starts and dies after a couple of seconds.

An amber lamp means you can drive on, but do not put it off. The car runs in a protective mode and usually drinks more.

What to do now

  1. Try the spare key. It is the quickest check and it splits the causes in half at once.
  2. Take the key off the bunch with other transponders — a neighbouring chip blocks the reading more often than a key actually fails.
  3. Replace the battery in the key if it has buttons: a flat one gives exactly this picture.
  4. Hold the key against the mark on the steering column or the spot given in the handbook: many cars have an emergency starting method.

Codes usually behind it

The lamp only says that something is wrong. The code says what exactly — read it with an adapter and look it up here.

What to read next

A lamp is not a diagnosis. The same symbol lights up for a dozen different reasons, and only the code stored in the car tells them apart.

How the app helps

CarScan reads the codes behind the lamp through an OBD-II adapter, explains them in plain words and puts them into a report you can show to a mechanic.
