Left Stranded by Faulty Key Fob

Hello to all.

Just thought I would relay what happened to my wife yesterday when she was left stranded after the car wouldn't start.

She was out and about and when returned to the car with the kids, the car wouldn't start. Didn't help that it was 39 degrees Celsius in Perth yesterday.

Anyway, the ignition would turn on, every thing seemed normal but when she hit the starter button .... Nothing!

So she checked that the car was in Park, foot on the brake, park brake on, still nothing. Tried the lock/unlock x 3 technique, still the same.

She rang Jeep assist who advised her again to try the lock/unlock x 4, still nothing. Then they asked her to remove the start button and then use the fob as a key. At this point the car would start but then shut itself down almost straight away.

Jeep Assist then advised that it was likely a faulty key fob. So I ran out the spare fob to her and then the car started no probs.

Just thought that I would relay that story for general information should others be stuck the same way.

Re: Left Stranded by Faulty Key Fob

thanks for the heads up.
one of the things i have in the console is spare CR2032 batteries - from a few posts around they have a habit of going flat in the key fob.
likely that wasn't your issue but it seems once they get even a bit down the electronics do funny things.

By using the fob as a key it does not need the battery.

Re: Left Stranded by Faulty Key Fob

Nice piece of info, Swampy.

Have you since changed the battery in the fob to see what happens?

It is strange that the car would fire but not continue to run when using the fob as a key, in that if the fob was faulty or flat then I wouldnt expect the car to fire at all.

I guess, the easiest way to prove that would be to take the battery out of the fob and try it.

If this is correct, then removing the battery and using the fob as a key may also be another way to get out of this problem if you are stranded by a fob battery that has not quite died yet.

Re: Left Stranded by Faulty Key Fob

Sorry about the quality.
Not easy opening the Key Fob one handed and video in the other.
Took three tries to do it.
Started OK and seemed to keep running.
Tried it again and drove around the block.

Re: Left Stranded by Faulty Key Fob

Hello again.

I think that Desertucker's video certainly proves that you don't need a battery in the key fob to start the vehicle if using the fob as a key.

As the key fob would work OK doing the lock/unlock sequence, we thought that the battery would be OK anyway.

Jeep Assist advised at the time that because the vehicle started then shut down straight away after using the fob as key, that it was a security issue as that indicates that the vehicle immobiliser has kicked in.

Funny thing is we tried the suspect fob this afternoon and it now appears to be working OK.

Go figure.

Go figure.
Think you got a faulty key fob read it ages ago somewhere on these forums.
Done it intermittently until it failed completely. Could be a bad solder joint or bad chip who knows.
Cant find the post.

Yes, that sounds about right.

We'll just put it to one side until the next time the vehicle is in with Jeep and make do with just one.

Re: Left Stranded by Faulty Key Fob

use the metal key and pry the plastic button at 6 O'clock.
It does take some effort but it will pop out.
