Immobilizer Is On

[prof-pat-pending]

right - my imobilzer has come on

wont start - turns over - followed by five beeps from behind the dash

 

i only have one key - so any ideas ?

 

its a 2.3 petrol on a 't' reg

 

its just a runabout - so i'm not bothered if i have to butcher the wiring

 

any help ?

has the key fallen apart recently?

If so theres a good chance the transponder has come out.

If not the common cause of problems is that relay 30 has given up (the solder joints go dry and don't make proper contact).

Theres info on here about it, its a case of take the fusebox apart, find the relay with the big 30 on top and either replace it or repair it (resolder the joints). If the door led on the drivers door is flashing rapidly when you try and turn this is usually a good sign of the problem. Its usually intermittent though.

 

If your not sure about the key it may be worth asking the local key cutter to put it in his machine to see if he can see the transponder chip if hes friendly enough? (if others have access to the key it may be that one of them has had it come apart and lost the chip?)

 

Only other thing worth a check is that the ring round the ignition barrel is intact - it plugs in under the dash near the steering column it may have managed to come out.
