Mentone Lock Installation for Homes, Rentals and Businesses

How this works in Mentone

Choosing a new lock comes down to five questions, and we walk through them with you before anything goes on the door. First, function: an exterior entry lock, a passage set that never locks, a privacy set for bathrooms, or a commercial storeroom lever that stays locked from outside. Second, grade: BHMA Grade 3 suits light residential use, Grade 2 is the practical choice for most homes, and Grade 1 belongs on busy commercial doors or anywhere you want maximum durability. Third, keyway: Kwikset and Schlage use different keyways, so mixing brands means carrying two keys unless we plan around it. Fourth, style and finish, including the exterior hardware rules some Mentone HOAs enforce. Fifth, handing and door thickness, which determine whether a lever or mortise lock fits without modification. Get those five right and the install is straightforward. Miss one and you end up with hardware that technically works but annoys you every single day.

Work included on a typical visit

• Fresh boring on new and blank doors. When a door arrives with no holes, we clamp a boring jig to it, mark the height to match your other doors, and cut a 2-1/8 inch cross bore and 1 inch edge bore at the backset your lock requires. The latch faceplate and the strike each get a chiseled or routed mortise so everything sits flush.
• Entry locksets, handlesets and deadbolt pairs. Front doors get the hardware people touch most. We install knob-and-deadbolt pairs, lever sets and full handlesets with a thumb-press grip, then adjust the deadbolt so it throws with a fingertip rather than a shoulder. Every cylinder on the door is keyed to one key before we call it finished.
• Grade 1 commercial cylindrical levers. California's accessibility rules favor hardware that works without tight grasping or twisting the wrist, which is one reason most commercial doors in Mentone carry levers. We mount Grade 1 levers at the existing prep height, confirm the return ends point toward the door, and set spring tension so the lever never droops after a busy month.
• Strike installation and frame reinforcement. If the jamb is soft, split or previously kicked, we tell you before mounting new hardware. Minor damage can be handled with a reinforcement plate or a longer strike that spreads force across more of the jamb. Serious rot needs carpentry first, because no lockset holds well in a crumbling frame, however good it is.
• Narrow-stile storefront deadlocks and cylinders. Aluminum glass doors on shops and offices use a narrow frame that only fits specific hardware, typically an Adams Rite style deadlock with a swinging hookbolt and a short backset such as 31/32 or 1-1/8 inch. We install the lock body, mortise cylinder and inside thumbturn or cylinder, then align the hookbolt with the jamb strike.

What's different about Mentone

Older Mentone homes often have 1-3/8 inch exterior doors, 2-3/8 inch backsets, and sometimes original mortise pockets or extra holes left by decades of swaps. Lock installation there is part detective work: we find where solid wood remains, choose hardware whose trim covers old scars, and reinforce jambs that have been rescrewed too many times. Thin doors may need a thin-door kit for a modern deadbolt, and original glass knobs can sometimes stay as decorative pieces beside it.

Foothill homes around Mentone see Santa Ana winds that slam doors hard enough to loosen trim and shift strikes, and wildfire-area codes shape the doors themselves. During installation we snug through-bolts, set strikes with long screws, and confirm the latch catches on a hard close without bouncing back open. Houses on slopes also settle unevenly, so we check hinge alignment and the reveal before marking any strike position on the jamb.

In family neighborhoods around Mentone, the most requested installs are keyed-alike exterior sets, privacy locks on bathrooms and lever conversions throughout the house. Parents also ask for locks on doors leading to pools, garages and home offices, where a keyed lever or a high-mounted secondary latch keeps small kids out without trapping anyone. We help choose functions that match how your household actually moves through the house.

Common situations

A woman buying her first home near Redlands East Valley High on Colton Avenue wants a deadbolt and new handle set for the 1950s wood front door, which has only a worn knob latch. We'd measure the thickness and backset, drill the cross and edge bores with a hole saw and jig, and mount the hardware so the bolt throws a full inch into a reinforced strike. Before packing up, we'd test the throw and alignment with the door open and closed, and hand over the keys.

• A remodel adds a pocket door between a primary bedroom and its bathroom, and the contractor's leftover hardware is a plain pull with no lock. We cut the narrow edge mortise for a privacy pocket lock with a thumbturn inside and an emergency release outside, then adjust the door stop so the latch meets the jamb without scraping paint.
• On a large lot outside Mentone, an owner adds a detached workshop with a steel exterior door that faces west and bakes in afternoon sun. We install a Grade 1 lever with a weather-resistant finish plus a deadbolt, key both to the house, and leave the strike positioned so the latch still catches when the hot steel door expands in July.
• Imagine French patio doors on a Mentone home where the inactive leaf is held only by a flimsy top latch. Push the active door hard and both swing open together. We install top and bottom flush bolts in the inactive leaf, drill receivers in the head jamb and the sill, and add a deadbolt to the active leaf that throws into the inactive leaf's edge.

How the visit works

1. Measure the door and confirm authorization. We start by measuring door thickness, backset, bore diameter and the spacing of any existing holes, then photograph the edge and jamb. Before cutting anything, we confirm you own the property or have written approval from the owner or manager, because new door prep can't be undone.
2. Choose hardware that fits the door and the job. Before anything is ordered or cut, you get a quote covering hardware, door prep, strike work and keying. If the door needs a fix first, like a sagging hinge or a cracked jamb, that line appears on the quote too, so nothing surprises you later.
3. Prep the door: bore, edge bore and mortises. We clamp a boring jig to the door at the chosen height, cut the cross bore from both faces to prevent splintering, then drill the edge bore. Faceplate mortises are routed or chiseled to the plate's exact depth so the latch sits flush and slides freely.
4. Set and reinforce the strike. Strike placement gets checked against the door's gap at the top, middle and bottom. If the door has sagged, we tighten or shim the hinges first rather than chasing the problem with an oversized strike opening that rattles and weakens the latch.
5. Mount, adjust and key the hardware. Lever handing, spring tension, thumbturn orientation and cylinder alignment all get set during mounting. For keyed-alike installs, we test every key in every lock. A lock that only turns with jiggling isn't finished, so we keep adjusting until it turns cleanly.
6. Test with the door closed and hand over. We lock and unlock every function with the door open and then closed, checking that nothing needs pushing or lifting. You try each key yourself, we explain features like privacy release holes or storeroom functions, and the shavings get cleaned up before we leave.

Pricing factors

• Hardware grade and who supplies it. Premium finishes, solid brass bodies, mortise construction and restricted keyways all raise hardware cost. We show you where extra money buys real durability and where it mostly buys looks, then let you decide. Either way, the full job is quoted before anything is ordered or cut.
• Door prep: blank, existing or mismatched. Switching lock styles costs more than replacing like for like. Going from a knob to a handleset, or from a vintage mortise lock to a cylindrical set, means new holes plus covering old ones. Staying with the same footprint keeps labor down and leaves more solid wood in the door.
• Commercial requirements. Electrified locks, electric strikes and anything tied to an access control panel can add costs beyond the lock itself, including wiring, power supplies and sometimes a low-voltage contractor. We identify those pieces early so the quote reflects the whole system rather than just the hardware we mount.

Common errors that cost time and money

• Mixing lock brands across a home and ending up with a ring of different keys. Kwikset and Schlage keyways don't cross over, so a mismatched set means more keys to lose, copy and track. Pick one brand for the exterior doors, or plan the keying before you buy.
• Putting the cheapest Grade 3 lock on the back or side door because nobody sees it. Doors out of view from the street are exactly where a forced entry happens with less chance of being noticed. Those doors deserve the same grade and strike reinforcement as the front.
• Drilling extra holes in a labeled fire door, or disabling the self-closer on the door between an attached garage and the house. Both quietly undo safety features that codes require. Check labels before adding hardware, and keep that garage door closing and latching on its own.

What to do before we arrive

• Turn the inside thumbturn or lever on every exterior door and ask yourself whether someone unfamiliar with the house could get out quickly in smoke or darkness. Hardware that's secure from outside but confusing from inside is a poor trade, especially on the door nearest the bedrooms.
• After installing privacy sets on bathroom and bedroom doors, keep the small emergency release tool somewhere grown-ups can find it, such as on top of the door trim. Kids lock themselves in more often than you'd expect, and the right pin opens the door in seconds without damage.
• Paint or stain the door before new hardware goes on, not after. Taping around a fresh lockset leaves ragged edges and paint creeps into the latch. If the door is getting refinished later, ask us to install, test and remove the hardware, then refit it once the finish cures.
• If you might add a smart deadbolt later, keep the door's prep standard: a 2-1/8 inch bore, a 2-3/8 or 2-3/4 inch backset and a 1-3/4 inch door. Most smart locks expect those numbers, and some need clearance from a storm door or the interior trim around the thumbturn.
