How to remove Lock Cylinder without the keys.

[JamesGUK]

Hi, I just bought a house and we have been given key only for the the side entrance. Previous owner hasn't got any keys for the front door. Now I need to replace the lock cylinder in the front door, but I can't take it out without any key. Please suggest what should I do.

Thanks,
James

Can you open the door? Need mor info, upvc, wooden door, lock type etc

If its a euro remove the handles and snap with grips or hammer, you will then need to turn the mechanism, bit tricky if you don't have the tool.
