Autumn Lock Maintenance | Ten Minutes, No Winter Lockout

I had a call-out last December, eleven at night, bloke on Keephatch Road standing in the rain. His multipoint lock had seized solid. He'd noticed the key was getting stiff back in September but figured it'd sort itself out. It didn't. The cold finished what the worn gearbox started, and I was charging him an emergency rate to get back into his own house.

That job could have been a five-pound tube of lubricant and twenty minutes on a Sunday afternoon.

Autumn is genuinely the right time to do this. Not spring, not mid-January when everything's already gone wrong. Locks, hinges, and door frames all shift as temperature and humidity drop. Small problems become expensive ones fast. Here's what to check.

The Checks

1. Lubricate the lock cylinder, not with WD-40

WD-40 is a water displacer. It'll free a stuck cylinder once, then leave a residue that gums up your pins over the next few months. Use a PTFE-based dry lubricant spray, or graphite powder for older pin-tumbler cylinders. Squirt it into the keyhole, insert the key a few times, wipe the excess off the face of the cylinder. Takes two minutes. Brands like ERA or Yale sell their own, and they're fine. Doesn't matter if your cylinder is an Ultion, a Mul-T-Lock, or a basic Yale rim lock, they all benefit from this.

2. Test the multipoint lock under load

Close your door and try the handle without lifting it first. On most uPVC and composite doors in Wokingham, you lift the handle to engage the multipoint, then turn the key. If the handle feels heavy, or if you can hear the gearbox grinding slightly, that's wear showing. The cold will tighten everything up and a tired gearbox will give up. GU, Fuhr, Maco, Winkhaus, Roto, they all wear the same way. Replacement before it fails: roughly £80 to £150 parts and labour on a standard door. Emergency replacement at midnight: more.

3. The stiff-key test

Your key should turn smoothly with two fingers. Not a full-hand grip. If you're having to muscle it, something is wrong: either the cylinder needs lubrication (see above), the door is dropping and misaligning the mechanism, or the cylinder itself is worn or damaged. Don't leave a stiff key. It's a warning.

4. Check every hinge

Open the door fully and push it gently up and down at the leading edge. Any movement there means the hinges are loose, worn, or both. On a heavy composite door, even 2mm of play puts the lock keepplate out of alignment. Tighten the screws, and if they're turning without biting, the holes are stripped and you need longer screws or a packing fix. While you're there, lubricate the hinge pins with a light oil. A squeaking hinge in October becomes a stiff, grinding one in January.

5. Inspect the weatherseal

Run your hand along the rubber seal around the door frame. Compressed, cracked, or missing sections don't just let in draughts. They change how the door sits against the frame, which affects how the lock engages. A door that used to close flush but now needs a shove is a door that's fighting you. Weatherseal is cheap. A new door frame is not.

6. Check the keepplate alignment

The keepplate is the metal plate on the door frame that the bolts shoot into. Open the door and look at it. There should be no scoring, no oval wear marks, no cracked surround. If there is, the lock has been working harder than it should. In a worst case, the frame timber behind the plate is chewed up and the plate itself is loose, which is a security problem, not just a wear problem. Press the plate. It should feel solid.

7. Garden gates and outbuildings

Easy to forget. If you've got a gate on Woosehill or a garage in Emmbrook with a padlock on it, give the shackle a tug and check for rust or seized internals. Spray PTFE into the keyway. A padlock that freezes solid in February isn't protecting anything, it's just an obstacle to you.

None of this takes skill. It takes a screwdriver, a can of PTFE spray, and the willingness to spend ten minutes before the first hard frost.
