Keyless entry only locking.
I have a 2015 Mazda 6 Touring with 291,000 miles. After owning it for several years with no issues electrically my keyless entry has stopped unlocking my doors. It happened randomly after I stopped for gas during a roadtrip. Got out and locked it using the keyless entry but when I came back out from the store the car would only lock using the keyless entry. Same lock signals like the flashers flashing once and the single beep but just wouldn’t unlock. I’ve always used the keyless entry and it usually functions as one tap lock and beep once and then another tap would unlock it and beep twice. The key fob unlocks the car fine. I’ve tried checking to see if the fob was in low power mode, it wasn’t. I changed the battery on the fob about 2 months ago and changed it this morning as well and it hasn’t fixed anything. I’ve tried resetting the fob by switching the car from on to off from the drivers seat 4+ times and then holding the lock and unlock button with it responding correctly but that also didn’t fix it. I have yet to disconnect the battery or replace the actuator in the door yet due to it just happening yesterday. Any tips or advice would be useful. Thanks!
