remote battery change

It varies.

It depends on the car.

What were we talking about?

The code won't be stored in a battery-volatile memory in the key, so you'll be able to replace that easily enough.

As for how long they last - I dunno, but the same battery's been in the key for my XM since I bought it 5 years and 60k miles ago - over half the car's life. So it's probably the original, and still working at 9.5yrs and 120k miles.

I've always had to be right there under the bonnet whenever I've changed the battery, and if I forgot anything as a result I don't remember ;))

(I used a small adjustable spanner and it wasn't too difficult).
