'Windermere Triangle' car lock mystery cracked

A set of traffic lights had earlier been blamed for the problem

A mystery which has been baffling motorists in a Lake District town for months has been solved.

Electronic car key fobs have failed to work around Crescent Road in Windermere, resulting in the area being dubbed the "Windermere Triangle".

Motorists have been unable to get in or out of their cars and security vans have been left stranded.

The culprit has now been revealed as the hand-held wireless devices used to take orders at a nearby bistro.

The system at Lazy Daisy's Lakeland Kitchen used the same radio frequency as many of the car key fobs.

Local ghost

Previously, a set of traffic lights and even a local ghost known as Albert had been blamed for the problem.

Ofcom was contacted and engineers used a sophisticated gadget called a spectrum analyser to pinpoint the source of the problem.

Tony Benton, owner of Lazy Daisy's, said: "About 18 months ago we got these hand-held terminals which send a message to the kitchen and the front of house till.

"It used the same kind of bog-standard radio frequency which was emitted by the car's keys themselves.

"Once this was identified I got the till company in to change the frequency, which resolved the issue.

"Apparently it's quite a common thing."
