Best way to remove a u-lockJELLIOT1

I wanted to convert an old schwinn to a single track for commuting to work. I lost the key to my u-lock a long time ago and need to free the bike in order to proceed. What is the best way to get the lock off, and no I did not steal the bike.

qualified to answer. but if it was in my barn I'd try popping it with a scissor jack from a car. or maybe an angle grinder could cut a notch in it. slide hammer in the key slot maybe?

I've never tried this but was told that this is how the thieves do it. Get a canister of liquid nitrogen or freon and freeze the bar by spraying it, then quickly give it a hard blow with a hammer and the bar will shatter. Supposedly either of those two will freeze the bar well below 50* f, maybe more, and that's enough for the hammer blow to break it.
yeah, just like in Fight Club. NMTrevo

I watched a bike thief in NYC do it...wolfereeno

The bike was a Wicked Witch Special <$50 piece of junk locked to a street sign. This was on BWay and 100 St. at about 8:30pm.

He used a bar from a weight set. It was about 5-6' long and had a slight bend near the top. He put it through the lock, held on to the bent top part, leaned his weight back, and then rocked gently.

He stopped when he saw me watching him intently from a resturant. He then sat on a car that was right near the bike (It happened to be MY car which was really why I was eyeing him).

When I was done eating, the guy was still sitting on my car. He was intent on getting that beater bike. I walked up to him, tried to look as tough as possible, and asked him to get off of my car.

He actually appologized for sitting on my car and said something like, "I was wondering why you were watching me..."

When I started up my car, he walked up the block smoking a cigarette. As soon as he turned the corner, I took his bike stealing pole, threw it in my back seat and took off :-)
nice move!Qubeley

it was a proud moment. thank you. i'm a pussy otherwise.

only problem was that I had to drive around with the giant pry bar in my back seat for months. i didn't know where to ditch it. i hate to say it but i figured the guys in my garage or neighborhood were just as likely to use it to steal bikes as anyone. finally i ditched it in the snow in a parking lot at a client in rural NJ.
I'm guessing it has an 8-pin circular key lock?Humma Hah

I've never had to get off a U-lock, but I had a cable lock with that kind of lock that was ruined by freezing once, so the key would no longer work. I ended up drilling the lock mechanism away, prying out the remains, and then the rest slipped apart. It took a couple of hours and some good drill bits.

man all you guys are way too pro about this. i always get a bottle jack, like from a truck, and put it in the lock and jack it until the lock pops.
