Ford Focus Remote Key Sensor

Hopefully someone can help!

I have a 2008 Ford Focus 1.8 TDCi, over the past few months I have had to get closer and closer to the car in order to unlock it with the remote key, now I have to be physically right next to the car and press the unlock button several times before it works.

I have changed the battery in the remote and I still get the same result. Any ideas?

Did you install a new radio? Are you parking near something that can cause interference?

No and no I'm afraid, wish it was that easy. I think it may be the sensor in the car itself but I have no clue where that is.

May take it to a reputable car electronics specialist in town that I know of.

Remotes get "beat up" so much an issue there is more likely. A second one is so handy, and paying for diagnostics can be so expensive, I'd actually suggest trying a new one (after re-checking the battery contacts in the current one) BEFORE giving up & going to an expert....

O.P. tried that, but it didn't help right away.

Might be as simple as poor (dirty) battery contacts in his remote, or some other issue with that particular remote.

Good first guess! - you never know, even the "new" battery COULD be a bad one....

Haha, definitely not the battery, I'm in the habit of testing those before I put them to use.

Contacts are also clean.

Just been out and the key seemed to be working better for some reason... Could the car being icy have had any effect on its ability to receive the signal? Sounds really peculiar I know...
