You don't have to insert your key in the trunk lock to open the doors in case your remote dies. You can insert it directly into one of the doors and unlock it as if there was no remote. Keep in mind that these are infrared remotes which means that a direct line of sight must be present between the remote and the receiver on the rear-view mirror for the remote to work. There is a battery in these remotes which does need to be changed every now and then.
