Immobiliser cut in

Is there any way getting around the immobiliser on my 2001 y reg jimny as padlock light on and will not start

Have you tried disconnecting the battery for a few minutes and then re-connecting it?

Yes don that and the padlock light stays on

Is your transponder working? Does the little light come on as flat battery in transponder will not let you disable immobiliser. Always start with the simplest solutions

Also. if the trnsponder batteries get shaken loos, you might have to reset it, the methodology is set out in the manual.

Only have a plane key that that has no buttons on or any thing but did start the jeep befor I fitted a new engine the bat was off for about a week I have spark and fuel to the fuel rail but 99.9 % sure the injectors not working so would def say immobiliser ?????

If you do need a new Transponder, they are only about $45 in Oz, not sure of price in UK.

Programming Transponder:

Leave one door open

Disconnect negative battery terminal, wait at least 5 seconds then re-connect
Within 20 second of re-connecting, put key in ignition then cycle the key from "ACC" to on position 20 times, then leave key in "Off" position after 20th turn
Jimny parkers will flash 20 times to indicate successful programming.

If this doesn't work, wait 5 seconds then turn the key from "Acc" to "On" 10 times, leave the key in "Off" position and wait 15 seconds then go through the 20 times thingy again.
The parkers will flash 20 times to indicate you've done the job. On the 20th flash of the parkers, press the button once on each immobiliser you have purchased, stolen or replaced the batteries in.
Turn the key to the "On" position to lok in and exit from the programming mode.

Hope this helps. I've done it nearly every year for the last 10 years as I lose my keys/battery goes flat or done something else stoopid :woohoo:
