How easy/hard is it to bypass an imobiliser?

[SGHOM]

Any ideas? /help

Unfortunatly, I'm talking saaaab here.

When I press the fob button, it opens the doors & disables the alarm & imobiliser..... But only on a Thursday with a following wind in the dead of night when the sun is out & gmtv is on !! The rest of the time it point blank refuses to open /pan

It's not the batteries or the fob, it's the signal between the fob & the car. Can this be easily bypassed??

Someone told me I would need a new ecu @ a cost of £150 + vat + fitting !! :inquisiti
I would be quite happy to open the car just using the key ........ Any ideas??

No simple answer to that one.
If the immobiliser is a little box on it's own (like an aftermarket one) then it's just a case of finding it \ the relays it connects to and doing away with them.


However, if it's a manufacturers alarm, and is linked to the ECU, then it can get very complicated very quickly.

How old is your car, Derek - it makes a big difference.

Manufacturers alarm Steve...... Apparently it's been a biatch since chris came in to possesion of the car :speechles

Hold fob under your chin, press button and signal may get through....

Well it works on roof of Tesco's in Sutton when alarm/imobiliser would not respond...

Something to do with bones in skull helping the signal along...

Give it a go in your local pub car park...

May attract attention of community mental health services but just tell them your head is an amplifier...

If its a saab in sheffield have you tried "phil smith - saab spares and repairs" local independant garage, I've used him for 5 years or so and he sorted my 9-5 alarm when it was playing up. He's on east coast road, down attercliff area
