Was working great, opened the car with the key instead of remote, now car sometimes can't detect the key fob

Question

We have a 2019 Mazda CX-5,

Succesfully installed using EVO-ALL and T-harness,

have been using 3x lock to remote start, everything was succesfully installed.

but after we unlocked the car with the key attached to keyfob.

the car sometimes can't detect the keyfob and won't start the car.

but it also sometimes does, can't figure out exactly in which situations it detcts the key and doesnt.

any ideas to solve this will be greatly appreciated!

Answer 1

Sounds like a weak battery in the vehicle keyfob
