New locks, knobs and deadbolts that work smoothly

Quick answer

Rekey or replace exterior locks when you move in. When replacing hardware, measure the backset and door thickness, and make sure the door is aligned so the latch and deadbolt slide in without forcing.

Many Monterey Park homes have their original 1960s knobs and deadbolts, often worn, mismatched or with keys nobody can account for.

Rekey or replace

Rekeying changes the pins so old keys stop working. Replacing makes sense if the hardware is worn, you want a new look, or you want a smart lock.

Measure first

Levers versus knobs

Levers are easier for children, older adults and anyone with full hands. Many households choose levers for interior doors.

Deadbolts

A deadbolt's strike plate should be fastened with long screws into the framing behind the jamb, not just the trim. That is what actually resists a kick.

Alignment

If you have to lift or push the door to lock it, the door has sagged or the strike is out of line. We fix alignment before installing new hardware, or the new lock will wear out quickly.

Smart locks

Smart locks need good alignment too, because the motor cannot force a sticky bolt. We check Wi-Fi or Bluetooth range and set it up with you.

Keying alike

When replacing exterior locks, keying the front, back and garage entry to one key makes life easier.

Sliding door locks

Sliding glass doors benefit from a secondary lock or a bar in the track.

Measuring before you buy

Most replacement locks fit standard door preps, but older doors may not. Measure the backset, which is the distance from the edge of the door to the center of the knob hole. Most are 2-3/8 or 2-3/4 inches; many locks adjust between the two.

Check the bore hole diameter, usually 2-1/8 inches, and the door thickness. Older mortise locks or unusual hardware need different parts, so take a photo of the edge of the door with the faceplate showing.

Deadbolts and strike plates

A deadbolt is only as strong as what it locks into. The short screws that come with strike plates often reach only into the door jamb. Replacing them with three-inch screws that reach the framing makes a big difference in kick-in resistance.

A reinforced strike plate adds more. We check that the bolt fully extends into the strike; if it binds, the door may need adjusting.

Rekeying

If you just moved in, rekeying existing locks is often cheaper than replacing them. Rekeying changes the pin setup so old keys no longer work. Many households also want all exterior doors on one key. If your locks are different brands, replacing some may make that easier.

Smart locks

Keypad and smart locks save fumbling for keys and let you give temporary codes. Before buying, check that the door's deadbolt aligns smoothly, since motorized bolts struggle if they rub. Battery-powered locks need regular battery changes; pick a model with a physical key or external power option as a backup.

Installing the new set

Our steps:

• Remove the old knob and latch, and note the backset and bore size
• Check door alignment and strike position
• Install the new latch and lock body
• Fit and adjust the strike plate, and add longer screws
• Test from both sides, including the deadbolt and any keypad

Doors that stick or miss the latch

If the latch does not catch or the bolt has to be forced, the door may have sagged. Tightening hinge screws, adding a long screw into the top hinge, or adjusting the strike usually fixes it. For sliders, see sliding glass doors that drag.

Levers versus knobs

Lever handles are easier to use with full hands, for children, and for older adults. Many people switch to levers when they replace knobs. Levers on exterior doors should be sturdy and have a strong spring, so they do not sag over time. Some levers are handed, meaning left- or right-handed, so check before buying.

Interior doors

Interior locks come as passage (no lock), privacy (push-button lock for bedrooms and bathrooms), and dummy (fixed handle). Bathroom and bedroom privacy locks should have an emergency release from outside, usually a small hole for a pin.

Keeping locks working

Spray dry graphite or a lock lubricant into the keyway once a year. Avoid oil, which attracts dust. If a key sticks, do not force it.

Sliding door and gate locks

Sliding glass doors often have weak latches. A secondary lock, such as a foot lock on the frame or a bar in the track, adds security. Side yard gates on hillside lots benefit from a keyed latch or padlock hasp. Gates should close and latch on their own, especially if there is a pool.

Matching finishes

Exterior lock finishes face sun and weather. Satin nickel, matte black, and oil-rubbed bronze hold up well. Polished brass may tarnish unless it has a lifetime finish.

Matching the front door lock, porch light, house numbers and mailbox gives the front of the house a finished look. Inside, keep one finish per room or floor for a consistent feel.
