They have probably stopped because they are stripped or a wire got disconnected. It happened to my SUV and the back locks were stripped. It also doesn't help if you use them a lot.

First check for a blown fuse. Check to see if there is power at the motor. If there is power at the motor then the motor itself is bad.
yes, it is a fuse it will be labled int. lights/ horn on the fuse box
There is a Relay for the Power Door Locks, which I purchased today from Checker Auto parts, but I can not find where the relay is located. I am assuming or hoping that it is the Relay for both the Door Locks and Power Windows.
If the power door locks quit working on a 1979 Corvette, it is due to broken pigtail switches. With age and use, the pigtails break and leaves the power door locks inoperable.
It's not that the key fob stopped working, but, if your car battery is dead, it's the car that has no power to pop the door locks.
Check your fuses.
Check the fuse and relay.

The first cars like the Stanley Steamer had mechanical door locks. The first car with power locks was a luxury car called the Scripps-Booth in 1914. It is unclear through most references which engineer working on the Scripps invented the power lock. Power locks were popularized by Packard luxury automobile Co in 1956. It is unclear through most references as to which engineers working for Packard invented their power locks.
