I have a 2010 model and wish like to buy a replacement fob battery. In the uk no supplier lists Cadillac so I cannot identify without taking my key fob apart. Does anyone know what the number is. I see batteries for GM cars are generally CR...
Can anyone help please

CR2032

Be very careful prying the fob apart. (I cracked one of mine and had to glue it back together)

Cadillacbrit, have you already tried getting in touch with the Customer Service team nearest you? I located their contact information on http://www.vauxhall.co.uk/tools/vauxhall-contact-us.html which lists both phone and email methods of communication. I apologize for any inconvenience this causes, but my department does not have access to the business policies of countries outside the United States. This is why we recommend contacting the Customer Service team nearest you; they are in the best position to assist.

Best,

Katie

The battery is a CR2037. It can be purchased at most stores for less than $3.00 usd. I buy them by the lot on Ebay and pay about $1.25 for Maxell or Sony in quantities of 6.

Maybe it changed but mine is a CR2032...I double checked.

I've never heard of a CR2037 battery. Google thinks that is a train. I'm not saying it doesn't exist, but it must be pretty rare. I had a CR2032 in my remote and just changed it last week. They are cheap. You can also use a CR2025, which is just a little thinner and so doesn't last as long, but should fit just fine.

Thankyou everyone for the info. I'll go for the CR2032 (actually the same as my Jeep Patriot). Also many thanks Katie for the link.

Just about every desktop PC motherboard uses this CR2032 for BIOS battery too, so in a pinch...
Yeah...just picked up a Rayovac CR2032 2-pack (Walmart ~$5), one for my CTS key fob and the other for a Dell PC.
