Any sifu that can help? My fren hv a 2010 mazda 3 sport. Problem is with the filp key fob. The batt is getting weak. So she bought a new battery.
1. Old batt still work. Got red led when pressed
2. Change new batt, no red led indication at all. Totally not responsive.
3. Test with multimeter, the new batt still hv 3V.
4. She got another battery. Still same, not working.
Please advise if anyone hv any solution. Thanks

Thats the problem. Its the same batt model, as well as brand too. Yet It is not working.

if that is the case habis lah.
Nvm I might try bend the contacts abit again. If not need to try a 3rd battery maybe GP this time.

Right now I can't. As its with my friend.
Odd but true. The old batt was bought at the same time with the 1st spare batt. So both is the same. The only diff is. The old one is a bit bengkak. Been using for 1yr plus. The new one is flat, already tested still hv 3v. Confirm nothing wrong with the remote, as when used the old batt, both LED works.

Maybe you are right. I hv to wait n test it when she brings it to office.
Thanks guys for all the advice.
