I have been trying to track down a battery for the back of the driving key to give me remote locking. I went to circuit city and tried to get a battery but they told me you need a special battery and not just any old battery would do. So I went to the toyota dealership and they weren't helpful because they don't have any of these vehicles on record. So if anyone knows what type of battery it is or where to track one down that would be great thanks.

Not sure if you have a Radio Shack store up in Canada, but they usually have all types of batteries or you can look for an electronics specialty store and see if they have them.

Thanks for the reply but the store "The Source" is basically what Radio Shack used to be and they do have a battery that looks like it fits but it doesn't mean it will work. I have bought a battery from them before, I was just more curious to know if anyone out there has a remote locking key and knows what type of battery it is...
