Is there any way of manually bypassing the alarm/immobiliser?

I've just bought a Rover 218 off some dodgy bloke in the paper and in the week I've had it, the immobiliser overrode the starter and the alarm light would flash and not let me start up. The AA had to get me to an electrics place and they said the starter circuit had a knackered wire in it or something, and after they'd done whatever they did, it seemed to start up fine again. No problem, I thought. But then this morning I found myself in exactly the same situation. The electrics place said I could possibly override the immobiliser just to get it started, but I'm at a complete loss as to how to do this. Now I do have a keycode (ie: stand outside car, turn key left and right loads of times and make no difference whatsoever), but so far it hasn't solved anything, and as far as I know, there was never a key fob with it, as it doesn't appear to have central locking. I tinkered with the fuses and managed to get the glow plugs working and the engine turning over, but not that decisive bit where the thing actually kicks into life. Is it just a case of running a wire from somewhere on the starter motor to the + terminal on the battery, or is it something much more complicated/impossible?

when you have this problem again, you must enter the code several times, it doesnt work everytime! also try doing with the doors locked, then with doors unlocked, try all kinds of situations, it works.

heh sorry SFulcher, but you went all the way and payed rover to have your fob battery changed?! lol

i have a similar problem with my zr, i always unlock with the fob, but sometimes i get in and the imobiliser is on and it starts to beep at me,???? sometimes its just a case of taking the key out and trying, but other times i have to get out the car lock it and un lock it a couple of times before it will start any ideas

thanks

15Peter20 I doubt you would have a manual key code if there wasn't supposed to be a fob with it.
I would contact Rover and tell them you may be interested in buying a key fob from them (this is just to get them to help you) ,but you need to know if it requires one. They should then be able to tell you from your registration.

If they do say you need one then get one of Ebay for a tenner and then ask Rover to program it for £25-35.

Yep my girlfriends brother's ZR does this also. You don't need to get out of the car though to lock and unlock it. It will still work from the inside.

I know where you're coming from, however I personally feel that if enough information is given for genuine people to find help, without compromising the security of people's vehicles, then we are doing the right thing. With the demise of MGR there are going to be owners who would have previously gone to dealers for advice who now find that either their dealer has closed or has changed franchise and doesn't want to know about MGR cars. Who are they going to turn to... In all likelihood us. We should help where we can.

If you open it but then don't start it immediately the passive immobiliser kicks in, all you need to do when you turn the ignition on and have it beep at you is hold the unlock button in til it stops beeping.

Sorry, but I th0ought it was a bit strange 3 new paeople on atr the same time asking how to bypass security systems. I am sure you can see my point.

If you are genuine, then I do apologise and i do hope you sort it out. My friend just had his car nicked and he had an imobiliser, so I am just a bit wary thats all

I have the same problem i have been told by a Rover dealer i cant get the code as the factory has now shut so how the hell am i suposed to disarm the immoboliser.



Anyone nice enough to help me start my car.
My local dealer said they would supply / programme a new plip for £91 & also retrieve the key access code for me at the same time.
They can get the key access code from the car using Testbook / Microcheck / Cobest or whatever they call it for £30.
I really must get the plip & code before they close down in 4 weeks!
