Patio Door Lock - fault
Hi all.
Our patio door lock has developed a fault. It now requires several dozen randomised manouverings of the handle in conjunction with frenzied twisting of the key to accomplish a locked or unlocked door status. Does the whole thing need to be replaced or just the lock or gear box? Its brand name is Saracen and has a plain square dead bolt shape. Arthur |

If it works easily, then you know the lock is fine. The fault will probably lie with the door/lock adjustments. I have fitted a number of patio door locks, to both old and new doors, and have never come up with a fail proof way of getting them aligned first time. The doors will have sagged slightly over time,and this has caused the lock to become stiff. It isnt the lock that is stiff, just the poor alignement of the 2 doors. If however it does not lock properly with door open, then you have either a fault with the lock itself, or a fault with the internal door mechanism. It is more likely to be the lock that mechanism, if it is a euro lock, they are quite cheap to buy, and even cheaper to make. Only 3 screw to replace it, check the length of your current lock, they are sold in different lengths. Alan. -- To reply by e-mail, change the ' + ' to 'plus'. |

Arthur Is it one where you have to lift the handle before locking? I have one and the door had sagged very slightly meaning that the mechanism wasn't travelling the full distance and not allowing the key to turn. Is it free to operate with the door open? Have the various bits been lubricated (other than the lock barrel) |

If the door is sagging is it possible to adjust it? Thanks. Arthur |

Patio Door Lock - fault
In an earlier contribution to this discussion,
Arthur 51 wrote: "Is it one where you have to lift the handle before locking? " Yes, it is. Arthur In that case, with the door open, observe carefully what happens when you lift the handle. There may be some shoot-bolts which come out of the top and bottom of the door, and engage with holes in the frame and/or there may be some little rollers on the lock edge of the door, which slide up and down and engage with U-shaped bits on the frame. If the door sags a bit, these moving bits may not align properly with the bits of the frame with which they are supposed to engage - stopping the handle from lifting properly, and - in turn - stopping the door from locking. There may be some adjustment on the door hinges (look for places where an Allen key may fit) - enabling you to take out the 'sag' - or the bits on the frame with which the moving bits engage may be adjustable for position. If they're easily removeable, remove one at a time until the door locks properly - then you'll know which is the culprit. -- Cheers, Roger ______ Email address maintained for newsgroup use only, and not regularly monitored..
