The frequency at which most car fobs operate is actually shared by a number of users so there's no guarantee of a clear frequency and not much that can really be done in the event of interference. It's actually part of the 70cm amateur radio band so it's quite legitimate for people to be transmitting on or near this frequency (sometimes as they sit in a car park having a chin wag on their radio) at quite high power.

This is compounded by the fact that the receivers built into cars are designed for cheapness rather than performance and are not very good at rejecting interering signals.

The moral of the story is to make sure that your lock cylinder is well greased. You may need it one day!
