My microwave sets off my car alarm! I aint joking you!
And the other night coming out of the services, I was walking towards my car and there was a Merc beside my car with a woman passanger sitting in it minding her own business.
As soon as I used the key fob to unlock my car from about 5m away, it set off the alarm on the Merc and the woman inside nearly had a weakness lol
I dont know if it was my keyfob radiowave but literally as I unlocked my car the merc alarm went off at the same time.
