Key fob not working
« December 27, 2018, 08:29:04 »
Hi there.

I have a 2009 i30cw wagon. Earlier today, my remote was working fine, went to use it tonight and it wonít work. Have tried both keys and a new battery. The red light shows on the button, but it wonít lock or unlock the doors. I have tried putting the ignition to accessories and holding down the unlock button and then again holding down the lock button but still no luck. Went for a 20 minute drive and that also hasnít fixed the problem. We also have a 2011 manual hatch that hasnít been driven for a few weeks and the key for that has stopped working also. Does anyone know what could be causing this? TIA

Hi, Helen. It all sounds highly coincidental. Have you tested this in different locations to eliminate interference?

That only hapened to me once and I was outside and dining place I had to gain access by puting the key in the lock and triggered to alarm whereup a staff member came out and said they had lot of similar events and that it was due to their wifi...

Dunno if that's any help, just my two penoth oh no sorry two cents

Too coincidental. asa below is also suggesting interference.

If a new location does not help, go to a locksmith, they can test the fob for a clean signal.

Only happened to me once. At Black Mountain in the ACT.
They actually had signs around warning people about the risk.

I think there are signs at the top of Mount Wellington too, but I've never had a problem up there.  :cool:

Helen, if you have an amateur radio operator in your neighbourhood this may also be a cause of your problem.
I recall the bloke next door having issues with his garage door key fobs not working correctly and we used to wonder if it was the ham radio person in the house behind us.

On another note, in a previous lifetime I worked at a television transmitting station and we regularly observed the RACT attending cars that the owners couldn't get into due to RF interference from our transmitters.
I think Holden Commodores were prone to it.

Yep. Mine was a Commodore on Black mountain.
But I've never had a problem on Mt Wellington either.

Thank you everyone for your replies. I went outside this morning and both cars opened with no problems. Iíve never had this issue before, but we have had some new people move in recently so they might have been using something that caused interference. Hopefully it doesnít happen again.
