on the way to work my car stalled after i stopped and tried to restart it. i worked it out to be the immobiliser, i got alocksmith to come out(easter Sat) so i wont tell u how much i paid for a new key FOB, any ways he tested it, the car kicked over first go ":bow: THANK THE LORD:bow: " we turned the car off check to see if it locked andonce again..Bingo...but thats when the bad news struck...again...I paid my cash and see you later my locksmith. i then tried to kick it over again and same thing... somy next step was to get my car home... so called a tow truckto take my car 1km up a hill.. there was no way i was pushing... OK now

What is my next step... i did a fault code and got code 31 which is Theft Deterrent Signal Missing SO what do i replace now to get my signal back???? any help would be great...my pocket is already hurting its been an expensive day due to
1 Loss Of wages (easterSat pently)
2 KeyFob
3 Tow Home
4 Lost my wallet..(update Found Wallet)

Would it be a matter of just Recoding the key again???? should i buy the contact ring??? i neeeeeeed help.

Hi, b4 you replace the key reader contacts, just try and gently bend them out so you have a better contact with the key, this worked for me on my vr about 5 months ago, I hvent had a problem since, " touch wood"

Try resetting your ecu, dissconect your neg battery terminal for about 5 minutes, then reconnect, see if that works you will be supprised.

i tried to bend them out on the sat arvo to make a better contact, i have already replaced the key reader, it was only $7 to replace thru holden so that was not to bad, i have an auto electrican come out home tomorrow, but i will go try the reseting thing now. its worth a shot, im keen to try any thing that dont cost much money. might even give it 10mins heheh, will let u know
