This Patlock Double Patio Door Security Device will give you the extra peace of mind you need when leaving your home – And all without the need for a key or remembering a combination code.

The weakest point of a house and the part which is most often used to force entry is your French or conservatory double doors. Give yourself the added comfort of the Patlock, which stops your doors from opening even if the locking mechanism is broken into.

Easily fitted to your doors and simple to fit on and pull off, the Patlock is a simple design which could make a world of difference to your home security. Keep valuable items safe and treasured memories locked up by investing in the Patlock, which holds French doors and other double doors closed and act as a visual deterrent to would-be burglars. For larger handles, remove the rubber inserts from each sleeve.

Rated 5 out of 5 by from Patlock Bought a Patlock Security Lock for the patio doors and it is a quality product, very sturdy and reassuring that the handles can't be accessed from the outside and very easy to use from the inside. Robert Dyas had the best price available and as there are fakes about it's good to know this is the genuine article. Also, good to know that Neighbourhood Watch and the Police endorse this product. Very pleased.

Rated 2 out of 5 by from Not easy to fit It arrived. The notes said I had to take the spindles out of the door. I don't know what a spindle is. Got to wait for my window fitter. Not impressed.

Rated 5 out of 5 by from Does what it says on the tin Bought this a couple weeks ago. Works really well and doesn't lool unsightly when on. Easy to put on and take off as no keys are required. I would recommend this due to patio doors being so vulnerable, even if the lock is broken this will stop the doors from opening as the handles can not be pulled down.

Rated 5 out of 5 by from Patlock Instant Patio or French Door Keyless Secur This is an excellent product which is a foolproof efficient locking device. Patio doors are notoriously easy to force. This device makes it much more difficult. With it in place it is highly visible and an effective deterrent. It is simple to fit and as an added bonus no keys to misplace

Rated 5 out of 5 by from Patlock French Patio Door Lock This is the second Patlock we have bought. One for the outside patio door and this one for the inside door. They provide extra security to both doors; are easy to fit and use. Discount code from Robert Dyas was a bonus and item was easy to collect from local Ryman store. Very happy.

Rated 5 out of 5 by from So easy to fit and very effective I brought this following a friends recommendation. Not only is it great value but it also gives great piece of mind knowing my doors are fully secure. Ordering online from Robert Dyas was easy and delivery into local store was quick.

Rated 5 out of 5 by from Security Item We are really glad that we brought this as it maakes us feel rather more secure about the pation doors we were worrying about. Have not yet worked out why it includes new spindles or why we need a locksmith to fit these however.

Rated 5 out of 5 by from Excellent product Add sense of security now we have these fitted. Easy to install with no codes or keys required, strong and sturdy product and a very clear visual indicator from outside the property that are easily removed when necessary.
