Electric Strike Installation in El Cerrito: Remote Release for the Door You Have

What to know first in El Cerrito

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.

How we can help in El Cerrito

• Fail-safe strike installation. A fail-safe strike is energized all day, which means heat, continuous draw and a clear plan for outages. We confirm the strike is rated for continuous duty, pair it with a supply that can carry it, and talk through who would be affected if the door unlatched during a blackout before choosing it.
• Strikes for cylindrical knob and lever locks. The knob or lever locks on most office and suite doors take a standard rectangular strike, which makes this the most straightforward electric strike installation. We confirm the lock's backset, measure latch projection and frame thickness, then fit a strike with the right keeper so the existing lock keeps working exactly as before.
• Strikes for mortise locks and deadlatches. Older commercial and historic buildings in El Cerrito 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.
• Frame cutting in hollow metal and wood. In grouted hollow-metal frames, the pocket may hide mortar or reinforcement that changes the plan. Wood jambs can be rotted or split near an old strike. We open the pocket, assess what's inside, and describe any repair before continuing, rather than forcing a strike into a frame that can't hold it.
• Power supply, wiring and latch monitoring. Latch monitoring lets the system know whether the door is actually latched rather than just closed. A strike with a latchbolt monitor switch, combined with a door-position switch, gives a clean picture: closed, latched, released. We add those when your system or your alarm monitor wants them.

How El Cerrito shapes the job

Older homes in El Cerrito often have wood jambs, thick paint and plaster that cracks if you look at it. A strike on a home office, a guest unit or a side entry is possible, but the wood needs gentle routing and the old latch may need replacing. We repair the jamb, touch up the paint, and tell you honestly when a smart lock would suit a residence better than a strike.

Schools, childcare centers, churches and youth programs in family neighborhoods use strikes to control who enters during the day while keeping exits free. A staff member sees a visitor on camera and releases the door. Parents should never meet a propped door, and children must always be able to leave. We emphasize fail-secure operation, short release times and clear instructions for substitute staff.

Foothill and hillside neighborhoods see more wind and, sometimes, planned power shutoffs during dangerous fire weather. For a strike-controlled door that matters: a fail-secure strike keeps the door locked and the key working when the grid is off, while a fail-safe strike would unlatch. We choose fail-secure for exterior entries here, and add a small backup supply if the reader must keep working through an outage.

Common situations

• Say a four-unit walk-up in Cajalco Gateway 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.
• In a building of salon suites, the rear door gets propped open because tenants and clients lose keys constantly. A reader with a fob for each stylist, a fail-secure strike and a door-position switch would change that. If the door stays open too long, the system chirps, and the owner can pull a record of which fob opened it and when.
• 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.
• Picture a retail suite with double hollow-metal doors, one leaf active and the other held by flush bolts. The owner wants the active leaf released from the front counter. We'd mount the strike in the frame at the active leaf, confirm the inactive leaf stays bolted, keep the lever for free exit, and talk through how deliveries will use the fixed side.

From your call to the finished job

1. Look at the door and the latch. On site we look at what you have: the latch, the strike plate, the frame, the gap, the closer and where power could come from. Photos help over the phone, but a walk-through spots the sagging hinge or the hidden reinforcement that pictures miss.
2. Choose the strike and approve the quote. We recommend a strike model, a failure mode and a release method, then write a quote covering hardware, frame work, wiring and testing. If part of the job belongs to an electrician or fire alarm contractor, the quote names that part. Nothing is cut until you approve.
3. Prepare the frame. This is the careful part: one correct cut and nothing extra. We use the manufacturer's template, check depth against the frame wall, and stop to reassess if we find mortar, a stud, wiring or a fire label. If the frame is too thin, we add reinforcement rather than hoping it holds.
4. Run the wiring and set up power. We tie the strike into whatever opens it: a desk button, a doorbell relay, a reader's controller or a keypad. Keeping the release signal separate from the power feed makes troubleshooting simple, and a short note inside the panel records what goes where.
5. Mount and align the strike. The strike is fastened in its pocket and the keeper adjusted so the latch enters freely, rests without rattling and leaves without catching. We close the door slowly and slammed, with the closer working and with it disconnected, and tune until the strike behaves under both.
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.

How we quote the job

• Lock type and strike model. The hardware itself varies widely. Light-duty strikes suit low-traffic interior doors; heavy-duty models handle busy entrances and hold more force. Fire-listed, latch-monitored and stainless versions add to the price. We pick the least expensive model that suits the door's traffic and the job's rules.
• Failure mode and power equipment. A fail-secure strike draws little current and shares a modest supply. A fail-safe strike runs continuously and may need a bigger supply and a backup battery. The failure mode you choose therefore affects the power equipment, and sometimes the wire size, as well as the strike.
• Wire distance and route. A short run through an accessible ceiling is quick. A long run through finished walls, concrete or several floors takes much longer, and may need an electrician or low-voltage contractor. We trace the route during the survey and show the cable work as its own line in the quote.

What not to do

• Ignoring door sag and closer pressure. A door that rides on its latch can't release, no matter how strong the strike is. The result is a buzzing coil and a frustrated receptionist. Correct the hinges, the stop and the closer first, then fit the strike.
• Assuming a strike makes a weak door strong. The strike is only one point in the frame, and a kicked door usually fails at the jamb, the screws or the hinges. Thin frames and short screws deserve attention, so we often add longer screws and a reinforcing plate.
• 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.

Practical tips before you call

• 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.
• Label the breaker, the supply and the wires. If a door stops opening next year, the person solving it will either find a labeled panel quickly or hunt above ceiling tiles for an afternoon. Ask us to leave a one-page diagram with your records.
• Test the door during an outage by switching off its breaker. With the power off, does the key still work from outside, and does the lever still let people out? If either answer is no, the design needs another look before an emergency, not during one.
• Test the door as it is today. If it needs a shove or a lift to latch, a strike will not cure that and may make it worse. Fix the closer, hinges or door sag first. A strike releases a latch, but it can't make a door close squarely.
