Chances are the battery holder inside the keyfob is becoming detached from the circuit board, very common with Vx. keys, usual trick is a folded up square of card inserted inside the fob between the battery and case.

As said above, try using the fob without it's case but press the battery whilst operating the button, that should get the red light on the fob working...

A few facts here for people.

The remotes are coded to the central door locking ecu or intruder alarm ecu (if alarm fitted) on the Omega. The ECU stores the specific codes of the remotes and hence there is no need to re-program them to the ecu IF the same remote is being used although it may need re-syncing.

In addition to this, the transponder chip is coded to the immobiliser ecu and works in the same way.

This is true for all the Vx remotes (although the likes of the Vectra C etc has an integrated immobiliser chip and not a seperate item plus they program into the CIM using a single command). The only time I have seen a second hand remote fail to program is when the wrong remote was sourced (there are quite a few different versions).

The older remotes (such as used on the Omega) can suffer from the battery holder becoming detached from the circuit board, if your good at soldering, this is an easy fix. Other failues can be the switches becoming worn (more so on facelift remotes) but again, these can be replaced plus the casings can become worn but repalcement items are now available online. If you put your time into repairing your existing remote then no re-coding is required.

Thanks for all the advice guy's

Key has been posted to Martin today and hopefully he will find what's wrong with it.....

Will update once I've had the key back

I have the same problem with my central locking it does not work by the key

I have a new spare key coded to the car and that does not make it work neither

Paul... why didn't you tell me that your PS was still on?   We could of taken that off the other day

Michael, does it work by the key in the lock and not work by the (remote) fob, not sure from the message but I am suffering man flu so sorry if I'm not quite right today!

[Michael2.6]

The problem with my C L is that it works when it wants

key in lock then turn and only opens the drivers door   pressing the remote does nothing

then sometimes it all works as it should   locking all doors with remote   and by putting the key in the lock opens all doors

Michael, I have had this issue but  I seem to be told off by all every time I pass on some experience. If you can see my email address, I'll tell you everything that has happened to me re this. Cheers.

Best of luck with the forum

Update -

Key has come back from Martin and has been repaired and a new case and switches fitted 

The key is like brand new and is now paired up and working to the car 

A huge big thanks to Martin for his efforts
