Has anyone any experience of the total cost of replacing locks etc when a key goes missing, and also whats involved. I presume the car locks, ignition and remote locking sensors will all need replacing? I have an Omega 2.2 Estate, 2003.

If you have a car pass you can get a key cut and coded, if you don't have a car pass your local dealer should be able to supply one of those too

[Jimbob]

depends what you want to acheive...

you can, as pete says, order a new key...

but, if you are trying to make the old one not work, then you need to change locks, ignition and ecu.


breakers on here often sell complete lock / key sets with all you need.

(you can also have the car conenncted up to a diag computer, and delete the old key, it will still manually unlock the doors, but wont turn the alarm off or start the car)

Does that mean that having key redone, would mean anyone finding 'old' key would not be able to use it?

I would say if someone found you old keys and linked them to your car they would be able to drive it away

Thanks for the advice guys.

Nah, not if the remote has been changed and the immobiliser re-programmed with tech 2 (which would be neeed with a new key and remote)

But they would be able to open the doors (not sure if the alarm would sound :-/)

Would you say that a replacement of locks, ignition and ecu is necessary to avoid entry into the car. I would not have a clue where to start myself so would have to rely on garage. Any idea of cost? I do still have one key.
The main worry is that if keys do not turn up, and, shall we say, fall into the wrong hands, all they have to do is walk round the car parks etc pressing the fob and look for the flashing indicators, and bingo!

When the new key is programmed you need all the other keys with you so that Tech II can 'allow' them to work. All keys not present are cancelled so if they did turn up you can't do as you fear.

Thank you for all your advice guys. Much appreciated. I am on my way home now to turn the house inside out. What a great evening! See what tomorrow brings!

not to mention that your key and remotes will need reprogramming at dealers

It's worth mentioning that you can do 2 things with a Tech 2:

1) Erase all known keyfobs / immobiliser transponders.
2) Pair a new keyfob / immobiliser transponder.

The car can store (IIRC) 5 of each.

The correct thing to do in this case would be to erase all known keys and then program in the existing key(s) and the new one.

If erasing the old key is important either take it to one of us with a Tech 2 or, if using a stealer, make sure the guy with the Tech 2 goes through the above sequence, though, because the easy option is to program the new key into one of the 3 spare slots and NOT to erase the old key.
