The batteries are CR2032 (x2).
No need for any reprogramming, the code in the key is non-volatile. I had one that had no batteries for a year, and it worked when the batteries were replaced.

Aren't they 2025? That's what was in mine.

Adding to the confusion.

My car came with two remotes with 2 CR2016’s.
There’s a yellow sticker inside with 2016 engraved under it.
The 2025 and 2032 are thicker.

Well, I have always fitted CR2032s, they fit, and seem to last a long time...

Mine is a single button IR remote and has 2x CR2025, it does look like slightly thicker ones would fit though.

As mentioned the remote isn't programmed - it's the receiver in the car. Some cars have to be reprogrammed after the main battery in the car has been disconnected and some don't!

(The 1993 we have will lose the programming even if the battery is off for a few minutes, my 1997 can have the battery off for hours or days and doesn't seem to lose it...)

Regards,
Simon

I've just changed the batteries in my IR plip. The batteries were 2025 but I put in two 2032s. I brought a card of 12 assorted big flat cell batteries - 2025, 2032 and 2015? - for 99p at What!

Well i replaced the batteries, but the remote still wont work. its gradually been dieing for a few months now, so looks like it needs a replace.

Can i used a second hand remote and program it as described above?

Yes, any 2 button IR remote should work if your receiver is reprogrammed.

If you have a soldering iron, try resoldering some connections on the pcb of your remote. The usual suspects seem to be the LED connections, the switch connections, the battery connection, and (be careful) the legs on the Integrated circuit. I have had a couple that were intermittant, but responded well to a bit of resoldering.

You can test it by looking at it through a digital camera while you push the buttons. It should show up as a white light. Practice on your TV remote so you know what you are looking for.

The remote also has a red LED near the rubber button cover, and that should give an indication of what the supply side is doing.
The problem with those batteries is that they always put out 3 Volts, even when flat.
