Issue started today....no audible chirp when locking the car. Either via the fob or touching the door handle. Been fine up to today. I checked all the settings(even thiught I hadn't touched anything) and they seem correct. Very odd?

Are all the doors locking ? If a door lock is not working, you many not get the confirmation chirp.

Lock the car, put the key away from the car and check every door.

All doors and locks working properly. Everything works fine. No key involved here, this keyless push button start system. Beep worked fine until yesterday????

Been throught the set-up screens, door-beep setting is correct.

Just a guess, does the warning buzzer(chirp) operate when opening/closing the power liftgate? If it doesn't, the buzzer is likely bad or has a bad connection. If it's still under warranty, I'd get the dealer involved.

The rear hatch beeps, works perfectly....issue only the when locking and unlocking the doors. Both with the fob or touching the door handle. Lights flash just no beep. All settings are correct. I intend to visit the dealer in the morning. Judging from some web searches today, this not an uncommon issue. All with same mysterious cause, many had different recommendations(various series of fob button combinations) non we're helpful. Thanks for everyones thoughts....appreciated.

Took car to my dealer the morning....seems to be more complicated than assumed. I'm long time customer, they immediately took in my car and began what seemed to be quick fix. Without going into detail, they could not figure solution, had they're many diagnostic computers attached. Net is car remains at the dealer....driving loaner Rav4 Hybrid. Should hear something later or tomorrow....will update.

Dealer just called with unbelievable diagnosis re no lock/unlock chirping issue. After all diagnosis failed, they opened the fender panel area and found debris from rodent(chipmunk?) nest. Wires were nibbled and cause of the issue. From what little I know until I go to dealer they inserted new section of harness.
This ALL may be at my expense!!! Not warranty issue. Part that irks me is they explained the wiring that new car manufactures use has coating made with peanut oils. Can't make this stuff up!!!!!

OMG. While I'm sure your predicament isn't very common, this doesn't seem like a good idea unless you live in Australia or Antarctica where there are no native squirrels.

Sadly my situation is NOT uncommon I now learn. Perhaps others not having same wiring area affected, but absolutely not uncommon. Dealer tech guys told me of many many instances where this wiring insulation has lured serious damage. Some far more costly than what I experienced. They advised I spray the engine compartment with Peppermint Extract, which I have now done. Seems Peppermint is odor rodents like chipmunks dislike. OR...as you say...move to Antartica. haha Live and learn....
