#1

My 2002 Sonata has stopped unlocking with either the remote or the switch on the door. Locks just fine. Brought this up before, someone suggested a new battery in remote. Tried, no go. I think it’s in the switch, but how to get at it? Should I let a willing friend take the door apart?


#2

It sounds like one of the relays in the module that handles the locks has failed. The module will need to be replaced.


#3

Is that expensive? Can my friend handle it do you think? (Handy, but not really conversant with car “stuff”) Also have a neighborhood mechanic…would that be a better option? And thanks for the reply!
