Yeah, had the local key specialist try, it appeared to program but the cars not responding to any button presses. Cheers. BC

As far as I know all the Delphi 3 button keys that fit the Omega horseshoe key are the same...

They are my advert ones and some I just dumped up there.

Might do tonight unless you can copy and host on the images server - you have my permission to use for forum use.

Get together a load, and we'll get them added to an FAQ somewhere.

I won't be able to do until next week, but if one of the other admins is online.... ;)

Used keyfobs in general are quite greasy, also I keep the iron in there for as short a time as possible.

As I pre tin the switches I have to melt the pads back then hold together and try to solder within 2 seconds.

It is a strong joint and it is well flowed not dry.

My soldering may not be that neat but it will last.

That Corsa was a right bugger though, it was greasy, covered in a strange substance and needed a good clean.

Remember those pads are only about 2mm square and the switch lug about 1.5mm wide, blown up shows any flaws much more than looking at it directly.

1 switch about 1/2mm off line, if they line up with the buttons OK I'd rather leave them like that than reheat the board.

My solder joints are fine, been soldering for over 30 years. Not done too much surface mount though.

The 2 button are the worst to fit, you need to get two pins solder molten at the same time

Lol, I assumed thats how they arrived!

You dont need to tin the switch contacts (they are tin dipped)

You do need to solder wick the old solder off the pads first (it wil be oxidised and not flow well again).

Then its a case of locate the switch and quick reflow of the old solder to hold it in place.....then solder the opposite end with fresh and repeat on the original.....

Should be better than production using the above methods.

Alcohol is very good for cleaning the boards to remove nasty substances and flux residue

There was corrosion inside the cover, it took quite a while to clean, especially around the battery holder.
