New, or alternate, fobs need to be coded as you say. Tech2 required for FL cars, not sure about MFL? Probably be the same actually, but early cars are different. You'll need to speak nicely to one of the tech2 oofers. There's a couple so you'd need to check who's closest

It's a credit card sized piece of card that contains all the necessary information for the car - codes, etc

There are several types of keyfob PCB too, so might not be compatible. 3rd one I bought was lucky.

The one you have might well be repairable, though. You're welcome to pop round sometime and I'll see what I can do.

Nice one Kevin

Indeed, the type is written on the back, but hard to read (different lighting often helps).

Generally, prefacelift cars with alarm and facelift estates with alarm use the fairly common Megamos 2 button.

Facelift saloons get a little more complex, as the Megamos 3 button is the one for alarmed cars, but I think Delphi bought out Megamos, and later ones are marked Delphi. However, these are different to some other Delphi 3 button ones.

Non alarmed cars use a different style (ie, GLS and 'Special' (ex-plod)).

Bosch ones, look identical, and very popular on other GM cars in the late 90s, are not compatible with any Omega.

What name am I looking for and on which bit of key/motherboard 

[Elite_L0ver]

There's numbers on the key which is 105 same as on original 1

I think that only refers to the actual blade though 
Are there no markings on the inside of the black case, the back part?

[RobG]

Take the PCB out and see what`s stamped on the back

[Elite_L0ver]

Just checked out the PCB on the original key it is a megamos board on the replacment its no name but is 433mhz and some other numbers

[jonny2112]

Typical! Ah well, looks like Kevin will be putting the kettle on!
