Keyfob 433mhz interferance

[160SR2006]

My keyfob does not work on my drive and works everywhere else away from my drive. My neighbour has a K12 and surprise surprise she has the same problem, she call AA and all keys batteries were checked seemed ok. Our door bell which works on 433 mhz also does not work. Weird!!! anyone experienced this or heard of similar problem, what do I do?

I get a lot of data transmissons around there too (433.920) it is also inside the amateur radio 70cm band. My guess would be that you have a strong data-link close by that is blanking your key-fob signal.
