45/45T Nickel Superior Thumbturn Euro Cylinder with 3 Keys/Anti Snap/Bump/Pick/Drill/Pull High Security uPVC Composite Door Barrel Profile Twist Thumb Turn Lock

These feel real good quality. They are solid and easy to self install. The key looks complicated and no one is going to copy this key with a piece of plastercin. Good to have the quick lock on the inside and not always require the key to lock the door from the inside. We have to replace locks every year due to living right next to the sea and salt water corrosion but I feel these will last a good few years.

had to change a lock in a upvc door , im not a guy who has done it before , but found it to be very easy to fit , one screw , i looked on youtube for how the basic fittting of a cylinder lock is done , and litteraly took me 5 minutes to get the old out and new in . i would make sure you measure the lock . but very easy to fit , and has a lot of security features . love the fact it has no key for internal locking but a built in one . cracking lock

Fitted today. Took five minutes.Seems very well built with a key that although massive, would be very hard to copy.

fitted easily, never swapped one b4, Ilooked at u tube b4 I purchased and learnt how to get the right size

Very sturdy and looks like it would be impossible to pick. Very good quality and extremely easy to install (one screw) as long as you ensure you have the right length barrel. keys are a fair bit larger than normal size - and there is a special code for ordering extra keys. Can't fault highly recommended.
