1. Know How to Detect a
Bad Car Immobilizer

2. A car immobilizer is a
technological security device that
will prevent your car from moving
and also prevents thieves from
being able to start the car.

3. There is a digital token which
gets sent from the key to the
immobilizer whenever you
attempt to start your car.

4. If the wrong token is sent or no
token at all is used, then your
starter motor, ignition, and fuel
system will remain disabled by
the immobilizer.

5. The immobilizer helps
responsible car owners to
prevent their cars from being
stolen and if you lose your car
key, then you need to go to the
dealership and get a new one.

6. Symptoms of a
bad immobilizer

7. For the security purpose, both
the car immobilizer system and
the transponder chip in the key
need to function properly.

8. When either one of them wears
out or gets damaged, then it
results in a lot of trouble within
the car.

9. Here are some of the symptoms that you can
expect to experience with a bad car immobilizer.
Engine won't start
Alarm won't function
Doors won't unlock
Doors won't lock

10. Engine won't
start

11. The immobilizer will normally
prevent the engine from
starting if the proper security
token is not given to it.

12. Even sometimes you may be able
to lock and unlock your vehicle,
but the engine still won’t start.

13. If there is no other mechanical
issue to explain the engine
problems, then it could be
associated with the wiring of
the immobilizer inside your car.

14. Alarm won't
function

15. The alarm system in your
vehicle is associated with the
same security feature as your
immobilizer, and a bad
immobilizer means you will have
a bad alarm system too.

16. And in case your key is
functioning properly, then you
need to physically examine the
immobilizer’s wiring inside the
vehicle.

17. If the wiring appears to have
damage, wear, and corrosion,
then this is a clear indication as
to why your immobilizer system
is not working.

18. Doors won't
unlock

19. When the unlock button is
pressed on your car key and the
car door does not unlock, this is
a sign that your key fob is not
registering with the immobilizer
system.

20. It might be the case that the
battery in your key needs to be
replaced or the immobilizer
system itself is having issues.

21. Whatever the case may be,
your key fob will not be able to
be transmitted properly
without a functional key and
immobilizer.

22. Doors won't
lock

23. At times, when cannot unlock
your door, then you probably
won’t be able to lock your door
with the key either.

24. This means that you’ll need to
either leave your doors
unlocked or leave the windows
down if the doors automatically
lock after a certain period of
time.

25. Get the problem fixed quickly
as your vehicle will be
vulnerable to thieves, vandals,
and bad weather if you leave
your windows down.
