I had parked my bike outside my local grocery store and when I came out I saw that my lock had been tampered with. The keyhole where I insert my key was broken in half and the rubber coating was also cut down. Luckily I managed to haul it back to home but can't open the lock now.

How can I get it open?

Edit:it was a u lock and I got it open with a set of bolt cutters but now when I tried to ride I saw a plate on my chain broken and the removal pin on the bike chain tool that I have is also broken any way I can fix it?

    As the lock has been rendered unusable anyway, no need to be gentle. Depending on what kind of lock it is, us a bolt cutter or an angle grinder. And be happy that your lock has done it's job, you still have the bike. – linac Apr 29 '15 at 7:58
  • You can haul it to a locksmith, or you can use a bolt cutter or angle grinder as stated. We can't advise you further without knowing what kind of lock it is -- cable, chain, U-bolt? – Daniel R Hicks Apr 29 '15 at 11:16
  • Hacksaw is an option too with the right blade. but if the lock is ruined, just save yourself the money and cut it off yourself. – Batman Apr 29 '15 at 12:33
  • Well, you'll probably need to replace the chain, or at least a few links. And, unfortunately, having the pin break on a chain tool (especially a cheap one) is not unusual. – Daniel R Hicks May 2 '15 at 12:05

It depends what kind of lock you have. If it took a thief a failed attempt I assume it's a good one, so take it to a locksmith or anyone with power tools, preferably with a proof of ownership of the bike.

The harder it is to destroy, the more convinced you should be that you should buy the exact same lock again :)
