A Tower Condo and a Mortise Lock That Was Wearing Out

This is a typical replacement, start to finish.

A retired engineer has lived in his condo on San Felipe for decades. The building went up in the early 1980s, and like many towers from that era, the unit doors use mortise locks: a lock body set into a pocket cut in the edge of the door, with a lever and a key cylinder. For months, his latch had been sticking. Turn the lever, pull, wait, pull again. He knew it wouldn't last.

He called on a weekday morning. The dispatcher asked what kind of lock it was and whether it was still working. Mortise, still working, mostly. He asked for a photo of the faceplate on the door edge. The engineer sent it. The brand and dimensions were visible. The dispatcher asked whether the building had rules for unit door hardware. It did: same finish, same lever style. The dispatcher said a technician was on the way.

Uniform, ID. He checked the engineer's license against a tax statement for the unit. Then he pulled the levers and the cylinder and slid the lock body out of the door.

Inside, the hub that the lever turns was worn round, and a return spring had snapped. The exact model was discontinued. The same maker's current version fit the same pocket and took the same cylinder and levers. Good news. The new faceplate was slightly longer, though. A fraction of an inch. He marked the edge, deepened the mortise with a sharp chisel, and test-fitted it twice until it sat flush.

He installed the new body, refitted the existing cylinder so the old key still worked, and put the levers back on. The building's look didn't change. The latch snapped in and out cleanly. He adjusted the strike so the door closed without a push.

The engineer worked the lever twenty times. Then twenty more, listening for the old click that meant trouble. It didn't come. The technician's advice: mortise locks last a long time if the door closes freely, so keep the closer and hinges adjusted, because a door that slams wears the lock.

When and How Locks Get Replaced

Warning Signs to Act On

Keys that need a jiggle. Latches that stick or don't catch. Deadbolts that need the door pushed or pulled. Handles that droop or spin. Rust or grit in the keyway. Any of those on an outside door means it's time.

Broken Door Lock Repair or a New Lock

Some fixes are small: a loose screw, a strike that's out of line, a door that's dropped on its hinges. Others aren't: worn hubs, snapped springs, cracked cams.

Mortise Locks in Older Towers

Many Uptown condos built in the 1970s and 1980s use mortise locks. When one fails, a current model that fits the same pocket is usually available, so the door doesn't need new holes and the building's look stays the same.

Replace Deadbolt Hardware

A failing deadbolt can be replaced by itself, using the existing holes. We fit a heavier strike with long screws at the same time, since that's where doors give way.

Front Door Lock Replacement for Handle Sets

Handle sets combine an exterior grip, an interior lever and usually a deadbolt. They're replaced as a set to keep the finish matched.

Rust and Grit Inside the Lock

Corroded lock replacement is common on doors that face the weather. Humidity and rain blown against doors without overhangs corrode locks from the inside. Corroded springs and latches don't come back. Replacement with a better finish lasts longer.

Keeping Your Current Key

We can usually reuse your cylinder or pin the new one to your existing key. If you'd rather start fresh, we key everything to a new key, or see rekey service.

Balcony and Patio Doors

Tower balconies and townhome patios have sliding or swinging doors with their own small locks, and those take the full force of afternoon sun and sideways rain. Slider latches wear out, hook bolts stop catching, and handles crack. A failed balcony lock high up may not seem urgent, but for families with small children it's a safety issue as much as a security one. Replacement latches are usually available by brand, and a secondary lock on the track adds a second layer.

Garage Entry Doors

The door between a townhome garage and the living space often has the most basic lock in the house and takes the hardest use. When it fails, people tend to leave it unlocked "for now." Replace it with a proper deadbolt and lever, and fit a heavy strike while you're at it.

Is It the Lock or the Door?

A surprising number of "broken locks" are doors that have sagged, swollen or shifted. Before replacing anything, the technician checks hinges, strike alignment and the gap around the door. Sometimes a longer hinge screw is the whole fix, and you keep your lock.

Condo Hardware Rules

Associations often control finish and style on hallway doors. Send a photo of the door and your HOA's rules, and we'll match them.

Who Can Approve the Replacement

Owners, or tenants with landlord approval. Photo ID with the address, or ID plus a deed or lease.

Ordering Parts for Unusual Locks

Some older or imported locks need a part we don't carry. When that happens, the technician makes the door secure, orders the right lock and comes back to fit it, rather than forcing in something that almost fits.

Lock Replacement Around Uptown

Lock replacement in Uptown is shaped by the buildings. Uptown has a lot of older towers, and older towers have a lot of mortise locks reaching the end of their life. We also replace deadbolts and handle sets on townhomes off San Felipe and Woodway, and on houses in Larchmont and Westhaven Estates where original hardware has finally given up. Every job starts with the same question: what fits this door without new holes? Most of the time, something does, and the door looks the same from the hallway when we're done.

Lock replacement is for locks that have stopped doing their job. A key that sticks, a deadbolt that won't throw, a knob that spins in your hand: each is a sign of a worn part, and a new lock is the cleanest fix.

Tell us exactly what the lock does. 'It turns but nothing happens' and 'the key won't go in' sound close on the phone but point to different repairs. The more detail you give, the better prepared the technician will be.

Bring along any parts you still have, including the old key. The brand and model stamped on the latch tell us which replacement matches best, and a matching part makes for a cleaner fit.

If your lock is part of a set, such as a handle and a deadbolt keyed alike, mention it. We can replace one to match the other, or change both for a consistent look.

We also replace locks in the Galleria, River Oaks and Memorial. For new doors with no hardware, see lock installation.

Replace It Before It Quits

Call Fast Locksmith 24/7. Tell us what the lock is doing, what type it is, and whether the door is secure now. A photo of the lock and the door edge helps.
