Possibly. It depends if you want to use it later to save cash or just a make do. Some have small drift pins in them which need pushing out but the metal barrel will seperate from the plastic surround somehow. A locksmith may be able to knock up a key by taking the barrel to them. You need to sit and think, do you want to buy a new one in the future - if so you can damage this one. Or do you want to try and get a key to fit this one - if so try a locksmith if you are not sure, first.
It is difficult to tell over the interweb.
