sometimes the remote control to unlock the doors and trunk,does not work

if there is a battery that needs to be replaced what is the size ?and where can we buy one?

thank you for your help

yes, unless they are nuclear,solar or wind powered. size varies pull it out and match it at a store

Yes there are batteries. You can go to auto zone and test the battery and can buy a new one if needed.

The remote should use a CR2032 battery. Can be purchased at just about any store that sells batteries.

l just snapped my remote apart and it has a single CR2032 battery in it. Could have saved some time. l just noticed that the battery type is stamped into the plastic on the back of the remote. LOL.
