Do what? Bypass a ravelco with an alarm going off? Of course. Don’t confuse a theft deterrent alarm with anti theft. Bypassing a ravelco is easy, 5-15 seconds depending on how lucky you get with the trap ground. Making a new fob, 60-75 seconds and its gone. “Microwave” detectors, shock sensors, glass break sensors are just that, sensors. Once the alarm goes off they are useless and an alarm isn’t going to stop the theft.
Looks like you have been a member for awhile but haven’t been active so I will save you the trouble. Finding exploits, weaknesses, bypasses ect is kinda what I do for fun. Its a puzzle for me, keeps my brain busy from my previous life adventures. Several here have talked to me in private, a majority of them in person. I don’t hide or embellish my past present or future or sugar coat things when I say them. I have done some crazy shit over the years for whats left of this country and life is too short to let others sell snake oil “anti theft” products and make it even worse (too bad our government is a laughing stock)
In short yes, it can be bypassed with your alarm going and driven away. The 3 minute mark I can say yes and no, the other environmental factors are unknown.
