the batterys in your keyless remote may need to be changed
#16 in the trunk called remote keyless entry system
HMMM Im not sure how to answer this one. Do you mean lose the keyless entry remote or it just stops working? If you lost the remote you can get replacements from the dealer or Ebay but you will have to have GM reprogram the transmitters. Now if it just stopped working all together you should check the fuse #41. If that's fine it could be anything. bad BCM , bad remote control door lock receiver, loose wire or a freak accident that erase your remote programming, Good luck
bad sensor module, cost you around $400.
Have to go into body computer with DRB3 to disable horn honk when locking vehicle.
Don't know if the 2 are connected but the remote not working anymore generally means that it needs the battery replacing, the lift gate (Auto ?) needs a fuse (?)
There could be a shortage in the wiring that goes to the fuse compartment that could be causing it to do that.
If you have a loss of power (blown fuse, replace battery, etc.) you have to reprogram the remote controls and overhead console. Turn ignition off to run 8 times then press button on remote control.
The batteris in both the remotes could have 'died' simyltaneously - or - check the fuse for the remote entry lock/unlock system to see if the fuse has blown.
From your description I'm not exactly sure what you mean. . . however. . . I'd suspect either a dead battery in the keyless remote -OR- the fuse that controls that circuit is blown. Consult your owners manual for which one it is and have a look.
If the dome light and the keyless entry system does not work on a Nissan Sentra it is possible there is blown fuse. The fuse box is found in the passenger compartment.
could be the circuit board on the hand held remote, check for black spots means board is baked battery in remote, or a fuse in main fuse panel. them if all else fails wiring at the release itself
