Here's the cheapest security upgrade most houses never get: longer screws. Deadbolt strike plates are commonly anchored with screws under an inch long, so they bite only the door jamb. Swap them for 3-inch screws that reach the wall stud, and a kick has to fight the house framing instead of a thin strip of wood. That idea runs through good home security locks generally: strengthen the weakest link before buying the fanciest hardware. Julian's Locksmith reinforces strikes, installs rated deadbolts and secures patio and garage doors for homeowners around Charter Oak, with every job priced up front.
How this works in Charter Oak
Lock ratings are confusing, so here's how to read them. The Builders Hardware Manufacturers Association (BHMA) tests hardware to ANSI standards and assigns grades. Grade 1 is the toughest, built for heavy commercial use. Grade 2 suits most homes and light commercial doors. Grade 3 is the entry level. For residential locks, BHMA also publishes a rating shown as three letters covering security, durability and finish, each scored A through C, so a package marked AAA earned top marks in all three. Separately, UL 437 is a listing for high-security cylinders that hold up to timed picking, drilling and forcing attacks; high-security lines from makers such as Medeco and Mul-T-Lock carry it. Words like 'heavy duty' have no test behind them. A practical rule for home security locks: Grade 1 or AAA deadbolts on exterior doors, Grade 2 or better knobs and levers, and UL 437 cylinders where key control or pick resistance is the real concern. Remember that every rating describes the lock alone. Mount it in a weak frame and most of what the rating promised disappears, which is why we check doors and jambs in Charter Oak before recommending hardware.
How we can help in Charter Oak
- Strike plate and door frame reinforcement. Older homes often have jambs drilled for three generations of locks, leaving little solid wood around the strike. We fill and rebuild where needed, then fit a wrap-around edge reinforcer on the door and a reinforced strike on the frame, so the deadbolt has sound material on both sides of the gap and the door closes without binding.
- Sliding glass door locks. Factory slider latches are small hooks that a pry bar can bend. We add a keyed secondary lock or a through-frame pin lock that ties the two panels together, and drive anti-lift screws into the upper track so the panel can't be lifted off its rollers. A cut-to-fit security bar in the track adds a visible third layer.
- Window locks that don't trap you. Window security is a balancing act, because bedroom windows double as fire escape routes. We install or replace sash locks, add pin locks or sliding window stops that let a window open a few inches for air, and fit quick-release mechanisms on security bars so they open from inside without a key or tool.
- High-security cylinders and restricted keys. For homeowners worried about who can copy their keys, we install high-security cylinders from Medeco, Mul-T-Lock or Schlage Primus. Their keys are patent-protected and can be duplicated only by an authorized dealer when you present your registration card, and the cylinders resist picking, bumping and drilling far better than standard pin tumblers.
- Gate, shed and outbuilding locks. A side gate that opens with a pull string gives anyone easy, hidden access to your back doors and windows. We install keyed or keypad gate locks, latch guards and lockable hasps, plus shrouded padlocks for sheds and pool equipment, and we can key them to your house so one key handles the whole property.
Local factors in Charter Oak
In family neighborhoods, the most common gap is a door left unlocked by someone in a hurry. Auto-locking smart deadbolts, keypads that end the lost-key problem for kids, and doors that latch with a gentle push all help. In many Charter Oak homes the garage entry door sees the most traffic, so it deserves the same home security locks as the front door. Doors leading to a pool also benefit from high-mounted, self-latching locks young children can't reach.
Renters can't always change locks freely, but they still deserve working home security locks. California law requires landlords to provide working deadbolts on main swinging entry doors and window security devices in rental units (Civil Code 1941.3). If yours are missing or broken, ask your landlord in writing. With the owner's permission, we can upgrade cylinders and strikes in Charter Oak apartments, and we can suggest removable secondary locks for sliders that need no drilling at all.
Triple-digit afternoons punish door hardware. Doors swell and shift through summer, so deadbolts that threw easily in spring start binding, and people stop bothering to lock them. Smart lock batteries drain faster on sun-baked doors, and some keypad screens wash out in direct glare. In Charter Oak, we adjust strikes for seasonal movement, choose finishes and electronics that tolerate heat, and suggest keypad models suited to west-facing entries that bake every afternoon.
Situations this covers
- Imagine a homeowner whose large dog door sits right below the back door's deadbolt thumbturn. Someone small enough, or anyone with a reach tool, could get through or flip the lock. Options include a locking steel cover for the pet door whenever the family travels, moving the deadbolt higher on the door, and adding a secondary bolt placed well out of arm's reach.
- Imagine a homeowner whose former roommate moved out on bad terms. Rekeying handles the old keys, but the owner worries a fresh key could simply be copied again later. Here a restricted keyway makes sense: Medeco or Mul-T-Lock cylinders fitted into the existing deadbolts, with keys that only an authorized dealer can cut when the owner presents the registration card.
- Consider a 1960s home near Glen Oak Elementary School whose front door is flanked by a tall glass sidelight. The owner asks for a double-cylinder deadbolt so nobody can break the glass and reach the thumbturn. We'd explain the fire-exit risk, then suggest alternatives: security film or laminated glass in the sidelight, a reinforced strike, and a Grade 1 single-cylinder deadbolt that keeps getting out quick and simple.
- For example, a homeowner in Charter Oak comes home to a back door that was kicked open while everyone was at work. The deadbolt itself survived, but the strike tore out of the jamb along with a long splinter of wood. A typical repair: rebuild the jamb, install a steel strike box and reinforcement plate with 3-inch screws, and upgrade to a Grade 1 deadbolt keyed to the front door.
Step by step with Julian's Locksmith
- Tell us about the house. Every security visit starts with your goals. Some homeowners want a full assessment, while others need one door fixed after a kick. Tell us which, and roughly how many entry points the house has. We'll give you an honest ETA for the visit and explain what we'll check once we're there.
- Walk every entry point. We walk the house with you instead of handing over a brochure. At each opening we look at how it would fail, not just what's installed: soft jambs, short screws, a latch that barely catches, glass near a thumbturn. You see what we see, and you can ask questions on the spot.
- Ranked plan and itemized quote. You get a short list in order of importance, usually starting with strike reinforcement and slider security, then deadbolt upgrades, then key control or smart features. Each item carries its own price, so you can approve some now and schedule the rest. Nothing starts until you say yes.
- Reinforce first, then install. Order matters. A new deadbolt installed into an unchanged frame is half a job, so we reinforce first. On sliders we adjust rollers before adding secondary locks. On French doors we align the leaves before fitting longer flush bolts. Each step makes the next one work properly.
- Set up keys, codes and key control. Strong locks deserve good key habits. We'll help you decide how many keys to cut and who should hold them, set up the authorization card for any patented key system, and program keypad codes. You leave knowing exactly how many keys exist for your house.
- Test everything and walk you through it. Before we leave, every door gets locked and unlocked from both sides with the door closed, not just standing open. We confirm bolts extend completely, sliders resist lifting and gate latches catch. Then we show you how each new lock works and answer any questions.
Pricing factors
- Door and frame condition. Steel doors, fiberglass doors and narrow glass doors each call for different drilling and reinforcement methods. Strike work in a metal jamb takes more care than in a wood one. We note these details during the walk-through so the quote reflects the doors you actually have, not a generic estimate.
- Key systems and key control. Standard keys are inexpensive to cut. Patented high-security keys cost more per key and can only be cut by authorized dealers with your registration card, which is exactly the point. Keying all locks alike adds a little time per cylinder but saves you from carrying a ring of mismatched keys.
- Timing and distance. A planned upgrade is usually scheduled at a convenient time, which keeps costs predictable. Urgent work after a break-in, when a door can't be secured, may need to happen right away. Either way, you get the price before work starts, and we'll explain any difference in the service call.

What not to do
- Choosing a smart lock for its app while ignoring its mechanical rating and backup cylinder. Some low-cost models have thin bolts or easily manipulated cylinders. Electronic features are a bonus; the bolt, the strike and the cylinder are what actually resist forced entry.
- Putting a high-security cylinder on the front door while leaving ordinary cylinders elsewhere. Key control works only when every exterior lock uses the restricted key. Otherwise, someone with a copied back-door key walks right in, and the front-door investment accomplishes very little.
- Installing double-cylinder deadbolts on exit doors without a plan for getting out. If the key isn't in the lock or immediately nearby during a fire, the door becomes a trap. Building codes generally expect exit doors to open from inside without a key, for good reason.
Practical tips before you call
- Recheck window locks after any work on the house. Painters, window cleaners and screen repair crews often leave sash locks unlatched. Walk the ground floor once a season, make sure every window actually locks, and confirm bedroom windows still open quickly from inside.
- Check your strike screws tonight. Open the door, remove one screw from the deadbolt strike plate and look at its length. If it's under an inch, it only holds the trim. Replace all of them with 3-inch screws that reach the stud, driving them carefully so you don't pull the jamb out of line.
- Fix any door that won't latch on its own. Doors that need a firm shove to close are often left resting against the frame, closed but unlocked, by family members in a hurry. Adjusting the strike, hinges or weatherstrip so the door latches with a gentle push removes a surprisingly common gap.
- Store the registration card for any high-security key system somewhere safe, never on your key ring. Without it, ordering extra keys takes extra steps, and anyone holding it could request copies. A home safe or the folder with your property documents works well.

Frequently asked questions
Are high-security locks worth it for a home?
For some homes, yes. Cylinders from Medeco, Mul-T-Lock and Schlage Primus resist picking, bumping and drilling, but their biggest residential benefit is key control: nobody can copy your keys without authorization. They make the most sense if you've lost track of keys, rent out rooms, employ household help or travel often. If your main concern is a kick-in, frame reinforcement comes first.
What does AAA mean on a lock package?
It's a BHMA rating for residential locks. The three letters rate security, durability and finish, in that order, each on a scale from A to C. AAA means the lock earned top marks in all three. A rating like BAA would mean security tested a step lower while durability and finish scored highest. It's a handy shortcut when comparing home security locks on a store shelf.
Do you need proof that I own the home before changing or upgrading locks?
Yes. Before we change, rekey or upgrade locks, we verify your ID and proof that you own or live at the property, such as closing documents, a utility bill or a lease. That rule protects you, since it also stops anyone else from having your locks changed. Renters may need landlord permission for some changes. California's Locksmith Act and BSIS licensing set the standards we work under.
Can you make my existing locks more secure without replacing them?
Often, yes. Reinforcing strikes with 3-inch screws, adding door edge wraps and long hinge screws, and adjusting doors so bolts extend completely can greatly improve the locks you already own. Some deadbolts accept high-security retrofit cylinders, and sliders can gain secondary locks and anti-lift protection without replacement. We'll tell you which existing hardware in your Charter Oak home is worth keeping.
Can window locks be secure and still safe in a fire?
Yes, if you choose carefully. Bedroom windows are emergency exits, so any lock or stop on them must release from inside without a key or tool. Window stops that allow a few inches of ventilation, standard sash locks, and security bars with quick-release mechanisms all work. Keyed window locks on sleeping-room windows are a bad idea, however secure they feel.
Do I really need a Grade 1 deadbolt on my house?
Grade 2 deadbolts handle typical residential use and are a reasonable choice for many doors. Grade 1 adds heavier construction and tougher test requirements, which matters most on doors hidden from view, doors with glass nearby, or doors that have been attacked before. The price gap between the two is often modest, so many homeowners choose Grade 1 for the main entry and the garage entry door.
