Hi,
2017 Highlander. Regular fobs not smart ones. Key fob stopped working. Got out spare andbit doesn't work either. Checked battery in main fob that we have used for 2 1/2 years and is at 2.99 volts of 3 volt battery. Should be ok. How could fobs lose pairing? Any help is appreciated.
Thanks,
Chuck

Just change one battery it's not that much. Just because the battery checks as 2.9 volts that does not mean that the battery is full enough to handle the slight load of working as it should.

Changed battery. Still not working.

About the same time, had the low tire pressure light come on. I checked/filled all tires including spare. Rest light and it blinked for 1 minute then stayed on. Manual said dealer on that happening. Went to dealer and the check found a bad computer. Have one on order. Hopefully this computer will also fix fobs connection but service guy didn't know if it would.
