Told him I had comfort access and he again he told me it is rechargeable. To me it looks like a standard replaceable battery that I assume does not charge. So what is up?
Never ceases to amaze me how uninformed dealers can be about their own product.
This isn't complicated. It's a battery. It's not rechargeable. They don't normally last more than a year, sometimes less. You can get them for a couple bucks at any store. Battery type 2032. Buy three, and throw an extra one in the glove box. Don't know why there is so much confusion about this. Well, I guess misinformation spread by uninformed dealers doesn't help.
