corsa utility 1.4 failing to start and it is not giving a spark. it flashes the spanner light about 5 second after turning the key on please tell me what is the problem

Hello Sibusiso,

(From the 2009 Corsa Owners Manual)

Your Immobilizer system checks whether the engine is allowed to start with the key being used. If the transponder in the key is recognised, the engine can be started.

The electronic immobiliser activates itself automatically after the key has been removed from the ignition switch. If control indicator "spanner light" flashes when the ignition is on, there is a fault in the system; the engine cannot be started.

Switch off the ignition and then repeat the start attempt.
If the control indicator continues flashing, attempt to start the engine using the spare key and seek the assistance of a workshop.

See 2009 Owners Manual at the link below.

2006 jeep liberty wrong key was inserted now won't start but turns over any ideas on how to reprogram key for my car?

NOOOOOO! Very easy to solve!!!!!
1.) Lock the car with the original key + remote control.
2.) open the car with the original remote control.
3.) Sit into the car, close ALL doors and windows.
4. Put in the ORIGINAL keys into the ignition and turn it right, until the dasboard lights go on.
5. Wait 10-15 seconds.
6. Take out the keys.
7. Leave the car and lock it with the original remote control.
8. Wait a minute or so.
9. open the car w. the original remote control.
10. Start your car and viola! Will start like a charm.
At least it happened to me with my 2006 cherokee.

IF NOT there is another method, one of these 2 will work!

Try Inserting the correct key in the ignition at least 3 times. Don't turn the key, just insert it-let it sit for 5 seconds and then remove-do this 3-5 times, then insert the key and attempt to start again

Hope it helps, BTW, the anti-theft immobilizer was working.

Below a schematic drawing how the anti-theft immobilizer works, just to give more insight.

Lost key to my 2006 Pontiac g6

Get the VIN and give it to the dealer and they can cut you a new key. You are looking at spending quite a bit in doing this, but even a locksmith is gonna charge you an arm and a leg.

I have the wrong key broken off in my toyota matrix..Is this expensive to fix

If it is in a door lock, the interior door panel can be removed and the lock cylinder can then be taken out and taken to a locksmith. You can count on at least one hour of labor for removal and installation plus the locksmith fee.

If it is in the ignition, it is trickier because in general you need to be able to turn the ignition key to the ACC position in order to remove the lock cylinder. If this cannot be done, then it may be necessary to destroy/drill out the lock cylinder in order to remove it. Then you will have to pay to purchase a new lock cylinder and have it re-keyed. This would cost you more than the door lock repair, for sure.
