Redlands Electric Strike Installation: Buzz-In, Card and Keypad Entry

Electric Strike Installation in Redlands: what to expect

An electric strike is a keeper, the metal pocket in your door frame that the latch bolt rests in when the door is shut, with a small electric mechanism built in. At rest, a fail-secure strike holds that keeper fixed, so the latch can't leave the frame even if someone pulls on the door. Send it 12 or 24 volts of low-voltage DC for a few seconds and the keeper's jaw pivots free, the latch slides past, and the door opens. Cut the power and the keeper resets. A fail-safe strike works the opposite way: it needs power to stay locked and lets go when power is removed. Inside the building nothing changes. Turn the lever or push the bar and the latch retracts the way it always has, because the lock isn't electrified, only the frame side is. That's what makes electric strike installation attractive for doors that must meet exit rules: free egress is built into the mechanical hardware, not the wiring. The tradeoff is that someone has to cut metal or wood in your frame, align the keeper to a latch, and bring power to the jamb.

Work included on a typical visit

• Fail-safe strike installation. Sometimes a door must open itself when power goes away: a corridor in a building with a fire-alarm release, for example. A fail-safe strike does that. We rarely put one on an exterior entrance, because an outage leaves it unlatched, but for interior zones it is the right tool, wired to a properly sized supply.
• Strikes for cylindrical knob and lever locks. Cylindrical locksets from Schlage, Kwikset, Sargent and Best use a spring latch that a strike can release easily. The thing to check is whether the latch has an anti-shim guard, which stops someone slipping a card past it. If yours doesn't, we may suggest a better lock while we're there.
• Strikes for mortise locks and deadlatches. Older commercial and historic buildings in Redlands often have mortise locks worth keeping. A properly chosen strike lets you keep the original lock, key and trim while adding a remote release. It is more precise work than a cylindrical lock, because the latchbolt, the deadlatch plunger and the keeper must all line up.
• Fire-rated frames and listed strikes. Rated doors must latch in a fire, which generally means fail-secure hardware that's listed for the rating. Corridor doors and stair enclosures in Redlands office buildings are the usual examples. We check the label on the hinge edge or frame, match the strike to the listing and stay inside the manufacturer's limits.
• Card, fob and keypad reader integration. For a single door, a keypad and a strike make a tidy upgrade over a keyed lock that everyone has copied. For several doors, a controller adds schedules and an audit trail. We install the door hardware and the reader side, and plan with you where the controller and software will live.

Local factors in Redlands

Older downtown buildings tend to have the doors strikes were made for: solid wood or steel doors, mortise locks worth keeping, and storefronts with narrow aluminum frames. In the business core of Redlands, the challenge is usually the frame, which may be plaster-backed, painted many times or part of a historic facade with rules about visible changes. We match the strike to the existing lock, protect original trim and hide the wiring where it won't show.

Inland heat is hard on electronics and hardware. Power supplies in a hot ceiling or an unventilated closet age faster, adhesive labels let go, and a door that swells in afternoon sun can start to bind on its latch, which shows up as a strike that will not release. We mount supplies where air moves, leave tolerance for seasonal movement and recheck alignment after the first hot spell.

Industrial parks put office doors beside bays and yards: steel doors, heavy use, dust and forklift traffic. A strike lets staff badge in while visitors wait at a window, and a heavy-duty fail-secure model stands up to slamming. We add stops where needed, keep wiring out of reach of equipment, use weather-sealed hardware on doors that open to yards, and size the supply for long runs across big buildings.

Situations this covers

• Say a four-unit walk-up in East Redlands has a worn mortise lock on the street door and a key that half the previous tenants still carry. We'd keep the lock, add a mortise strike, and connect a keypad and an intercom so residents can admit guests from their phones. The landlord keeps a key override, and a departed tenant loses access the day their code is deleted.
• Think of a boutique in a strip center off SR-38 with an aluminum storefront door and an Adams Rite deadlatch. The owner often works alone and wants to buzz in delivery drivers from the back counter without leaving a customer. The jamb extrusion is thin, so we'd choose a narrow-frame strike, add a reinforcing plate behind it, and check that the door still closes cleanly against its weatherstripping.
• Another common callback follows a gusty Santa Ana afternoon: the strike clicks, but the door will not open. Wind pressure and a strong closer are pushing the door hard against the latch, so the keeper cannot let go. We'd ease the closer, check the hinges and stop, readjust the keeper, and then retest the release with the building's air handlers running.
• Take a dealership service office where the door is opened constantly by advisors, porters and customers from opening until closing. A light-duty strike wears out quickly under that traffic. We'd specify a heavy-duty, fail-secure strike with a stainless keeper, feed it from a properly sized supply, and set a brief release time so the door relatches between visitors.

From your call to the finished job

1. Look at the door and the latch. We start at the door, not the catalog. We note the lock brand and type, measure the backset and door thickness, inspect the frame material and watch how the door swings, closes and sits in its opening. If it doesn't latch reliably today, we fix that first.
2. Choose the strike and approve the quote. You get a clear choice and a clear price before any work. We explain why we picked a particular strike, what alternatives exist and what each would change in daily use. If you want a keypad now and a card reader later, we plan the wiring so that upgrade is simple.
3. Prepare the frame. We tape the area, mark the opening from the actual latch height, and cut the pocket to the strike's template. Metal frames get a clean-edged cutout and, where needed, a back-box. Wood frames are routed. Dust and filings are vacuumed up, and bare metal is primed.
4. Run the wiring and set up power. Power sits where it can be reached and locked away, and each conductor is labeled at both ends. On a long run we increase the wire size to avoid voltage drop, because a strike that gets too little voltage may buzz and fail to release. Anything needing an electrician is flagged, not improvised.
5. Mount and align the strike. We seat the strike, adjust the keeper opening as the manufacturer allows, and test the latch from both sides. If the door is pushing on the latch, we correct the cause, whether hinges, closer or stop, instead of forcing the strike to compensate for it.
6. Test, demonstrate and hand over. We test every path: power on, power off, release button, reader, key from outside, lever from inside, and a fire alarm signal if one is connected. Then we show you how the door behaves and what to do if it doesn't, and leave you the strike model, voltage and wiring notes.

What affects the cost

• Failure mode and power equipment. Backup power is optional on fail-secure doors, because the door stays locked and the key works. It matters more on fail-safe doors you want to hold through a short outage, though they will still release once the battery drains. We lay out both options so you can decide.
• Release method and add-ons. A desk button is the simplest release. A keypad costs more, a card reader and controller more again, and a networked system with software more still. Add-ons such as a door-position switch, exit sensor or intercom relay each appear on the quote, so you can add or skip them.
• Fire rating, codes, door count and timing. Rated openings need listed hardware and sometimes inspection, which adds time and cost. Several doors in one visit cost less per door than scattered visits. We tell you honestly when a permit, plan review or another trade is likely and what that might add.

Common errors that cost time and money

• Buying the strike before checking the lock. A strike for a cylindrical latch won't work with a mortise lock, and one made for a standard 1-3/4 inch door may not suit a thinner one. Measure the backset, note the brand, and confirm the latch type before ordering.
• Powering the strike from an undersized or shared supply. Too little current, or voltage lost along a long thin wire, makes the strike click without releasing, then work again unpredictably. Faults like that are hard to diagnose, and a properly sized supply and wire prevent them.
• Choosing fail-safe because it sounds safer. A fail-safe strike releases when power is lost, so a blackout, a tripped breaker or a dead adapter leaves your entrance unlatched. For exterior doors, fail-secure with a keyed lock is usually the better answer.

What to do before we arrive

• Ask for a door-position switch if your door tends to get propped open. A door left ajar triggers a chirp or an alert, which stops a strike door from becoming an unlocked door by habit. The sensor is a small cost next to the equipment it protects.
• Before you call, take three photos: the latch edge of the door, the strike plate on the frame, and the whole door in its frame. Add the lock brand if it's stamped on the latch face. With those, we can often name the right strike and bring it with us on the first visit to Redlands.
• Don't oil the keeper. Oil collects dust and grit, and inland heat bakes it into gum. A shot of dry PTFE or graphite on the latch is better. If the strike starts to stick, clean the pocket and check the alignment before you reach for any lubricant.
• Push on the door while someone presses the release. If it only opens when you lean toward the hinges, the door is binding on the latch and the strike is not at fault. That's called preload, and the fix is usually a closer or hinge adjustment, not a stronger strike.

Getting to Redlands

Redlands is about 19 miles from our San Bernardino base, roughly 25 minutes in light traffic via Belmont Ave and Palm Ave to I-215 South. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment.

Our path into Redlands depends on where the previous job wrapped up. Sometimes that's a straight run via Colton Avenue; other times it's surface streets the whole way. Either way, you get a heads-up call when the technician is close.
