Its work paying a few extra quid for new one if its not much more, seeing as the buttons do get problematic over time

Is there a 'how to' for programming the FOB on here?

A proper Tech II, although IIRC some of the better generic code readers will programme them.

Is it IR or RF remote?

Infra red have a little dome near the sunroof switch.
Title: Re: New spare key
Post by: Loch View on 25 February 2009, 09:16:32
Then it must be Rf. There is nothing near the switch
Title: Re: New spare key
Post by: TheBoy on 25 February 2009, 10:27:12
96 will be RF, thus (real) Tech2 or similar.

94 and earlier 95 are IR, so need Tech1 or similar

would it be possible to program in a 2 button key from a 2002 model or is that too advanced?

Only if same make and style. Can't remember if the facelift estate ones (saloon all 3 button) are compatible...

They are, most are Megamos AM....but check the type.

I'd better let that idea pass. Too much hassle no doubt :)

Have you had it programmed to car?  If not, PM Hotel21, who has the facilities.  You will need carpass.
Title: Re: New spare key
Post by: BC on 26 February 2009, 11:23:24
Yeah, had the local key specialist try, it appeared to program but the cars not responding to any button presses. Cheers. BC

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.

Post by: Martin_1962 on 26 February 2009, 15:15:49
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.

I use meths, the other components are not good - sometimes the joints are snapped.

I do retin them as I find the solder flows around the pins better, and I can clean the flux off before fitting.

I usually find very little solder left after switch removal - I normally cut them off, excess solder wiped off with kitchen towel.

My joints may not be overly neat but defiantely better than standard ;D

I'll get the wick though - good idea

BTW I have repaired around 50 fobs now!
