2015 Toyota Camry SE key fob battery contact issue — PCB works only when pressure is applied
I think I finally narrowed down the issue with my 2015 Toyota Camry SE key fob.
The PCB itself may actually still work, because:
- the red LED sometimes flashes,
- especially when I manually press down on the battery.
The real problem now seems to be that the battery cannot maintain enough pressure/contact with the PCB.
The original shell was cracked badly, and now the battery and PCB connection is unstable:
- sometimes the LED flashes,
- sometimes completely dead,
- depending on pressure/contact.
Even after installing a brand new CR2016 battery, the issue remains because the battery cannot stay firmly pressed against the contacts.
I already bought a new replacement key shell, but the internal battery-to-PCB contact still cannot stay firmly fixed. The key fob only works when I manually apply pressure to the battery, and once the shell is closed normally, the contact becomes unstable again.
At this point I suspect:
- battery holder/tray issue,
- poor contact pressure,
- shell/internal structure problem, rather than a completely dead PCB.
Does anyone know:
- whether the internal black battery holder/tray can be purchased separately,
- or if I need to buy a complete shell with the full internal structure?
Thanks!
