Sampson Posted May 1, 2017 Share Posted May 1, 2017 Hi guys. Having a few issues with keyless entry into my focus mk2.5. I have 2 key fobs along with an extra "hard" key. I've replaced the batteries in both the key fobs which didn't help the following issue. I go out in the morning and it won't unlock without pressing the key and will sometimes say key not found when trying to start (all with key in my pocket). I'll get to work and can lock the car using the handle lock button. Work finishes and I can get back in my car without touching the key. Get back home and it won't lock with the handle button! Almost like at home somethings stopping it working. Just seems really intermittent. Anybody experience this before? Quote Link to comment Share on other sites More sharing options...
mjt Posted May 2, 2017 Share Posted May 2, 2017 I don't know the frequencies used in the keyless system but it sounds as if something like a wireless router signal might be jamming it. If you have a router you could try turning it off at the mains as a test. (If it's a neighbour's that might be more difficult ). Quote Link to comment Share on other sites More sharing options...
Sampson Posted May 2, 2017 Author Share Posted May 2, 2017 The thought had crossed my mind! Only issue with that is I've got 25 neighboughs! As I live in a flat block haha. I'll try it out in a few other locations to pin it down to an issue at home. Quote Link to comment Share on other sites More sharing options...

Stoney871 Posted May 2, 2017 Share Posted May 2, 2017 Do you have a dash cam or satnav plugged in?This can cause problems with interference on the key sensors.Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...

Sent from my SM-G930F using Tapatalk Yes I do, I've got a dash cam hardwired in So it only comes on with the ignition. Shouldn't cause an issue with interference if it's off should it? I'll disconnect for one morning at give it a go though. Quote Link to comment Share on other sites More sharing options...
mjt Posted May 3, 2017 Share Posted May 3, 2017 Those would cause the problem wherever the car was. As it only seems to happen close to home it can't be anything inside the car. Quote Link to comment Share on other sites More sharing options...
