Changing locks

Lex Luthor

got those ISEO locks on my doors that you turn the handle up, turn the key and the door locks. Are they easy enough to change without having to get a locksmith?

I had a look and it looks like there is a screw in from the side that is securing the barrel in position. Is it just a matter of loosening that off and removing old lock and putting in new one?

Easy enough to change.

Put the key into the lock, remove the 60 mm pozi screw. Turn the key about 15-20 degrees, keeping a slight pull on the barrel, hey presto barrel out.

Yep just changed one last week....

You'll need the key to change the barrel, as to slide the barrel from the centre of the lock you'll need to twist the key to a particular position ( as per kad-mans post ).

Do-more

Lex you will want to take the existing barrel out and measure it, (or bring it with you) before you buy the new one, as they come in different lengths for different door types.

I tried all above advice this morning, removed the pozi screw but not having any luck removing the barrel. I don't know if I have to have the key in a particular position when trying to remove the barrel, but I don't want to force anything. Even resisted the temptation to get out the hammer to give it a slight tap.

I can also see what looks like a pin installed just above where I removed the screw, which could also be a retaining pin for the barrel, but its not removable.

Its an ISEO lock on a teak Munster Joinery door, if thats any help

Kadman, when you say turn the key 15-20deg and then pull, what position should the key be in before turning and then in what direction (cw or ccw) do you turn?

Hi Lex,

Try a 15 degree turn in either direction , and slight pressure on the barrell, and you should feel the pin of the barrell engaging in a slot. If the barrel is reluctant to pull/push out , then a slight tap with a hammer will show any movement , and you know you are engaged in the slot, and it should move for you.

The pin above the pozi screw is more than likely a rivet of the case of the lock to the front vertical strip on the lockface.

Munster joinery locks are three or 5 pin , cam lock, or push out bolt. And this method should release the barrel in their locks.

Any use? exactly what was said earlier but a visual might help.

if the door is not locking properly, it doesn't necessarily mean that the barrel is faulty. usually the door needs to be adjusted or the lock needs to be oiled or both. if it is the cylinder, it doesn't matter who made the door or whether theres cams or anything. all you need to know is the type of cylinder - euro profile for nearly all modern doors - and the size - 40/40 or 30/45 etc etc

take the cylinder out and turn the key around a few times on both ends. if it turns smooth, the problem is the lock and receivers are not lining up. if the cylinder feels rough - replace, measure from one end to the centre hole and from the other end to the hole. thats your size. ideally you should measure from where the screw came out of the door to just past the where it sits in the handle - sometimes the one you have might be sticking out too far past the handle - a burglars delight - yank with a vice grip and he's in.

it doesn't matter if you have five point hook locks in your door. if they break your cylinder they're in. think of how easily you turn your key to engage the lock, thats how easy it is to open them if they can snap that cylinder.

so think carefully before you grab that 10 euro cylinder. the door is only as secure as its weakest link. i use multilock break secure cylinders for my customers,

if anyone wants any advice on locking options, p.m. me.
