I'm trying to change the lock in my patio sliding doors. A friend told me all I have to do is remove the screw/bolt on the inside of the door to free up the barrell and then I could slide it out. I did so, but the barrel won't slide out. It has become a bit lose and gives about 5mm each way. I couldn't see any other screws that would keep the barrell in place, so I'm wondering am I missing something? It's a yale lock (and also has the black lever type thing to close the door) Attached a couple of pictures as I don't think I'm explaining this very well! I also don't have the key to this lock anymore, hence the need to change it...

There's a tab that protrudes from the body of the lock to operate the locking mechanism, you'll need to turn the key to the point where this is in line with the body to remove it. Just pull at the barrel lightly while turning the key, you should feel the point where it starts to move.

Thanks Leo, only problem I have is that I don't have the key anymore, it got lost... Is there any other way of doing this?
 
had same prob, thing is only way is u have to drill out barrell where key is inserted with 6mm steel bit to about half way trough then barrell should come out andreplace with new one, this might seem diffcult but not.
 
Thanks Declan, I'll give that a go. Can I use an SDS Hammerdrill bit, or do I have to use a steel bit (have a normal drill as well) - not sure if I have one handy, but wouldn't be a big deal picking on up.
 
hammerdrill bit is for concrete etc. .... steel bit is your only man. make sure your drill isn't in hammer action mode when you drill and don't forget to wear the goggles!
 
These are very easy to do. Take the door handle off (it is usually held by 2 screws on the inside). Grip the lock barrel at the top and bottom with a vise grips and bend it down. it will snap very easily then you can pull out the other side that is remaining.
 
I tried the latest suggestion using Multi grip (water pump) pliers, but I had no luck snapping the barrell. I tried bending in all sorts of directions, but figured I'd end up with a damaged door, so I'll have to do the drilling after all! Needless to say I take little comfort in how easy it appears to break locks, thank god I have additional mechanisms to secure the door!
 
Thanks PB comments like that are always welcome.

Lets comment on the senario..
Firstly, sliding patio doors similar to the one in the photos above are the main method of break-ins to peoples property.

I would have , on average 5/6 calls per week in the Wicklow / Blessington area to replace the cylinders on such doors.

From the photo above, it looks like one of the older sliders. If this is the case and the op damages the internal mechanism by snapping using a vice grips she wont be able to get a new one.

If when snapping, the cam falls into the lock case (as often happens) what then? (Incidently the snapping using a vice grips is called the Bulgarian Technique)

Should the op decide to drill, the points to consider are
1. Type of Drill bit
2. Size of drill bit
3. Where to drill
4. When to stop drilling
5. What to do after drilling
6. What happens if the drill bit breaks in the lock.
7. Be careful that the bit does not bounce accross the door and break the glass.

Alternatively, call a local locksmith, get a couple of quotes - pay no more than 75 euro to include a new cylinder with 3 keys.

Paddybloggit is this any help? .......If a leg breaks go to the doctor, If a tooth breaks go to a dentist....... If a lock breaks..........
 
Perfect locksmith!
Going with a drill bit or going with a locksmith ..... I know which I'd choose.

Hope this helps sort OP's dilemma.
