2011 XK. I've always gotten the chirp when pushing the button on the fob 2 times. Recently the chirp has stopped. Any ideas?
Thanks

 

The chirp on the second press of fob or door button confirms the deadlocks engaging - at least on my car. There's no chirp on the initial locking. But my understanding is that NA cars don't have deadlocking and the car should double-chirp if you try to engage them.

I suppose the 'chirper' may have died. If you try locking the car with a door ajar or a fob left inside, do you hear the double chirp then?

 

I always only got a single chirp on the second button press. I'll have to your suggestions. Thanks👍

 

Note that the OP, Wm. Lyon, is in Southern California USA. The reply posted by @justinhill, who is in Surrey, England, does not apply to North American market vehicles because the double-lock feature has been disabled here. Double-locking means that the doors cannot be opened from the inside. The National Highway Transportation Safety Administration (USA) deemed double-locking to be unsafe. Every year, kids die from heat stroke when left in a car. Being able to open the doors from the inside when locked can save lives. See my Post #8:

European models have double locking. The beep on the second push is to remind you to make sure you didn't leave your kid in the car.

 

Totally agree with you, Stuart. (That's why I said in my post "But my understanding is that NA cars don't have deadlocking and the car should double-chirp if you try to engage them...")

 

The alarm sounder is sometimes known to go bad and need replacement. There is at least one thread in this forum all about it.

 

Correct. Mine died a few years ago. Not the worst thing to go wrong with our cars.

 

Glad that's clarified. In your response I originally thought by "NA" you meant "naturally aspirated".

 

That's for sure. I'm not worried about it, just thought maybe there was an easy fix.👍

 

Of course - yes, I'm sorry for not being clear!

 

I am in the UK and my car doesn’t chirp as it’s turned off and never has chirped. I think I would need to change it in SDD if I wanted it to sound.

My sounder went faulty last year as at times it would sound like a Geiger Counter. There has been posts that a faulty sounder can run the battery down.
It sits under the bonnet/hood catch on the right hand side. A bit fiddly to change but very doable.

Its a Ford part and I changed mine for new one for Ford Fiesta that I found on EBay for £20

where it’s situated it’s under the windscreen and gets a lot of the rain run off from the screen etc.

This has definitely been posted about on here and the change procedure explained

 

LOL, I’d call the disabled “chirp” a blessing. Thus mine is disabled.

 

I got rid of that one from the passenger seat a while ago - lol

 

NA= naturally aspirated,
NAS= North American Spec
