Key fob not starting car properly

[AUStingerGT]

Hi guys. Both sets of key fobs are not able to start the car unless they are pressed onto the push button start inside the car. The car also won’t lock with them anymore. At first I thought it was the battery for the key fob but both of them are doing it intermittently. Is this more an issue with the battery in the car do you think?
It’s an my18 stinger and to memory no batteries have been changed yet.

If you have to put it next to the start button it sounds like a battery to me.

Yer cheers. Simple way to work it out is fit two new batteries to the key fob and see what happens. I’ll sort it today and see.

It's the 2032 battery in the keyfob.

Almost certainly.

Yep found a new battery at home and replaced it. Works fine now. Just weird how it worked sometimes and other times it wouldn’t and got no warning to say battery was low which I thought it did.

Yeah, these 2032 primary cell lithium coins are not always linear as they become depleted

They can even show adequate voltage when measured, but not adequate voltage when even a low load is applied (like pressing the unlock button).

With a new battery, your are good for another few years - depending on usage frequency.


For WAY more information than you want or need about 2032 coin cells, and their behaviour over time - you can put yourself to sleep reading

I replaced both fob batteries when I noticed that my range to lock the car got shorter, followed by having to press the hatch button a few times to get a response: figured close on four years was long enough battery life.

Changed by fob battery about 2 months ago. Got about 50 months out of it.

I had the same experience - I think the Stinger's fob has a higher draw than my last car (same CR2032)

Our Stinger fobs have a far better energy use rate than my friends dodge charger... she has to replace her fob battery about every 10 months.. I keep saying she should get a faraday cage for it as i believe it may be because her key is stored pretty close to the car in her garage...
