A friend just let me know about a new trick thieves have to get into your car. You may remember a series of car break-ins in Seattle where several cars parked outside of condominiums were entered without damage, and the owners swore that they were locked when the owners went to bed.

The trick for entering a modern locked car depends on two things: (1) The car must be new enough that it only requires that the car key fob be present in the vicinity for the car to unlock and be started. (2) That the thief has a new  device which captures the fob signal and amplifies it so that it appears to be in the vicinity of the car.  The whole thing is explained in an article on the Edmunds.com web site: https://www.edmunds.com/car-news/technology/how-to-protect-your-car-from-keyless-entry-hacking.html
