Quick answer:
- Blowing dust is the single biggest enemy of a key cylinder here.
- Graphite and household oils make dust problems worse, not better.
- A key that is getting harder to turn is a warning, not a quirk.
Dust Is the Real Problem
Every spring the wind picks up and fine grit gets into everything, including the keyway of an exterior lock. Inside a cylinder, that dust mixes with whatever lubricant is in there and becomes a paste. The pins stop dropping cleanly, the key needs a little more force, and eventually it needs a lot more force.
This is the normal life cycle of an exterior lock in the high desert, and it is why locks here often need service years before the manufacturer would suggest.
Please Do Not Use Graphite
The internet loves telling people to puff graphite powder or spray oil into a sticky lock. In a dusty climate both make the situation worse. Oil attracts and holds grit, and graphite cakes once it gets damp during monsoon season. Either one turns a lock that needed cleaning into a lock that needs replacing.
If you lubricate anything, use a dry PTFE-based lubricant, sparingly. Better still, have the cylinder cleaned properly rather than adding something to the contamination already in there.
Sun, and What It Does to Keypads
Albuquerque sun is hard on anything plastic facing west or south. On keypad and smart locks, the usual casualties are the printed numbers on the buttons and the rubber or silicone over the keypad, which goes brittle and cracks. Once moisture can reach the contacts behind it, the lock starts reading phantom presses or no presses at all.
It also has a quieter effect worth knowing about. Buttons that have worn unevenly tell anyone looking which four digits are in your code, which is a small security problem that builds slowly over a few years.
The Daily Temperature Swing
A 30-degree difference between afternoon and dawn moves a door. Wooden doors and frames expand and contract through the day and across the seasons, and a latch that lines up perfectly at noon in October can bind at 6am in July.
This shows up most on two things: deadbolts that suddenly need the door pulled toward you before the bolt will throw, and battery-powered locks that start eating batteries because the motor is fighting a binding bolt every cycle. In both cases the lock is innocent. The opening needs adjusting, and that is part of our lock installation and residential work.
What to Watch For
None of this arrives suddenly. The warning signs are gradual, and catching them early is the difference between a service call and a replacement:
- The key needs jiggling, lifting, or a particular angle to work
- You have started using the key on the handle because the deadbolt is stiff
- A keypad needs a firmer press than it used to
- Battery life on a smart lock has dropped noticeably
- The door has to be pushed or pulled before the bolt will throw
A key that is getting harder to turn is the most important one on that list, because the next step is usually a key snapped off in the lock. Call (505) 818-0720 before it gets there.
Frequently Asked Questions
How often should exterior locks be serviced in Albuquerque?
There is no fixed schedule, but exterior hardware here generally needs attention sooner than the same lock would in a milder climate. The practical trigger is behavior: if a key has started needing extra force or a particular angle, have it looked at.
Is WD-40 safe to use on a lock?
It is not a good choice. It is a solvent more than a lubricant, and the residue attracts the dust that caused the problem. A dry PTFE lubricant is gentler, and a proper cleaning is better than either.
Can a stiff lock be cleaned, or does it need replacing?
Often it can be serviced rather than replaced, especially if you catch it before the key starts flexing. We look at the actual condition and tell you honestly which it is.
