Yale Locks P1109 Replacement Rim Cylinder 4 Keys Polished Brass

This is a dirt-cheap way to replace a lock. It comes with four keys too which makes it a real bargain. It is fairly simple to fit. You need a flat-headed screwdriver to undo four screws: two holding the lock casing to the door and the two holding the barrel in place. You also need a saw to cut the barrel's screws to length - or you might be able to re-use the existing screws. Unless you have a very thick door you will always have to saw the bar that comes out of the barrel to length - see picture. A junior hacksaw will do the job. That's a bit fiddly if you don't have a vice, I used mole grips to hold it. Just in case you weren't aware, you can only change the lock easily if you can open the door. If you've either lost your keys or the lock is jammed such that you can't open the door, you will either need power tools to break it apart or a locksmith.

Good value. Supplier posted same day as order sent. Locks don't last for ever. Better to buy a good quality unit like this, even if it's no longer made in Willenhall - cheap ones don't last even half as long as this quality. You should get 25+ years constant use. Easy to fit. (tools needed: 1 average sized screwdriver, & possibly a small metal hacksaw or pair of pliers if you have a thinnish door - such as internal quality type width). Takes no more than 5 minutes - undo 2 screws to side of internal catch with door open, unhook and then unscrew the 2 long screws that hold the old cylinder barrel. Keep ALL screws. You may have to renew internal retaining plate (2 more screws), although unlikely. Insert new barrel from outside of door. Dummy run refitting the internal catch - if it continues to sit proud of the door, compare length of metal strip with graduations scored into it with old cylinder, and cut new metal strip to same length with hacksaw, or, if your grip is good, you can use pliers to work up & down till it breaks, TAKING CARE NOT TO BEND WHOLE strip - its better to use the junior hacksaw. Reassemble everything in reverse order. Make sure it all works, then close door & distribute new keys. Feel pleased with yourself. Job done.

Excellent item. Got it as a replacement and fitted it into an existing Yale latch block. No drama with the installation. Everything is provided and comes with a decent set of keys.

This was a great quick switch for a worn out old lock, took about 5 minutes and just needed a screwdriver. If your door is thinner than ours, you would need a hacksaw or cutter to shorten the spindle on the back, but we have a big old door, so no changes needed. :) Supplied with 4 keys, which would cost £24 just for the keys if we got them cut locally, so great value for money!

Good quality product and the delivery on time. Thank you

Super easy install, came with all needed bits and 4 keys is a massive bonus costs a lot to get a few keys cut these days

Used as a like for like replacement. It comes with 4 keys (thankfully) and so no need to spend an extra fiver (or there abouts) to cut a spare one. Item was delivered 3 days earlier than anticipated and so cant complain and the price was decent. Credits to the supplier/courier of doing their job punctually.

Delivered in time. It fitted my door nicely and works well. Good value!

It's realy a durable product.

Un produit convenable, pour éviter d'user les goupilles intérieures, mieux vaut passer les dents des clé avec du papier abrasif fin et lubrifier l'intérieur avec du graphite en poudre et surtout pas du gras.

Got the pack with 4 keys. Easy to install. I had to cut off the stem to make it shorter since it's a thinner door than default stem length. It wasn't hard. Glad I was able to keep old night lock on the door we have. The lock is probably at least 50 years old and is a neat historical item to still be able to use.

I bought this to replace a cylinder in a door that used a push bar exit device. I was able to cut the long part of the cylinder to fit my door and installed it easily. Came with four keys so I didn't have to pay to have keys copied.

good to have this kind of spare.
