Not All Deadbolts Are Created Equal
If you're shopping for a deadbolt, you've probably noticed that prices range from $15 at the hardware store to $300+ for premium models. The difference isn't just brand markup — it's security. A cheap deadbolt can be picked or bumped in seconds. A good one resists picking, drilling, and forced entry for minutes.
Here's what to look for when choosing a deadbolt for your home.
Deadbolt Grades: What They Mean
The American National Standards Institute (ANSI) grades locks on a three-tier scale:
- Grade 1 — Highest security. Built for commercial use but ideal for home entry doors. These withstand 10+ strikes and 800,000+ open/close cycles. If you're serious about home security, start here.
- Grade 2 — Good residential security. Meets most home needs. Withstands 5+ strikes and 400,000 cycles. A solid choice for side and back doors.
- Grade 3 — Basic security. The minimum standard. Fine for interior doors or low-risk areas, but not what you want on your front door.
Look for the grade stamped on the lock or packaging. If it's not marked, assume Grade 3.
Single Cylinder vs Double Cylinder
The cylinder is where the key goes. There are two types:
- Single cylinder — Keyed on the outside, thumb-turn on the inside. This is the standard for most homes. Quick to lock and unlock from inside, which matters in an emergency.
- Double cylinder — Keyed on both sides. You need a key to lock or unlock from inside. This prevents someone from breaking a window and reaching in to turn the thumb-turn. However, it's a fire hazard — if you need to exit quickly, you need a key to get out. Some building codes prohibit double cylinders on exit doors.
For most homes, a single cylinder deadbolt is the right choice. Consider a double cylinder only if your door has glass panels within arm's reach of the lock.
Key Features to Look For
- Anti-pick pins — Security pins that resist lock picking. Standard on Grade 1 and good Grade 2 locks.
- Anti-drill plate — Hardened steel plate that stops drill bits from reaching the cylinder.
- Saw-resistant bolt — The bolt has hardened steel inserts that resist sawing.
- Bolt length — At least 1 inch. Shorter bolts can be pried open more easily.
- Reinforced strike plate — The plate on the door frame should be secured with 3-inch screws that reach the wall stud, not just the trim.
Smart Locks: Worth It?
Smart locks (keyless entry via app, keypad, or fingerprint) are growing in popularity. They're convenient — no keys to lose, remote access for guests, and activity logs. But they have trade-offs:
- Pros: No keys needed, grant temporary access, receive entry alerts, integrate with smart home systems.
- Cons: Battery-dependent (if the battery dies, you're locked out unless there's a key backup), more expensive ($150-$300+), and the electronic components can fail.
Many smart locks also include a traditional key cylinder as backup. If you go smart, choose one with a key override so you're never completely locked out.
Popular Deadbolt Brands
- Schlage — Grade 1 residential options (B560 series). Solid, reliable, reasonably priced.
- Kwikset — Budget-friendly, widely available. SmartKey rekeying is convenient but security is Grade 2/3.
- Yale — Premium residential and smart lock options. High quality, higher price.
- Medeco — High-security, Grade 1. Resists picking, drilling, and bumping. More expensive but the real deal.
- Mul-T-Lock — Another high-security option with restricted key duplication.
Installation: DIY or Professional?
A deadbolt is only as strong as its installation. If the strike plate is secured with short screws into the door trim, a swift kick will pop it open regardless of the lock's grade.
If you're comfortable with a drill and chisel, installing a deadbolt is a DIY project. The key steps: drill the cross-bore hole, chisel the mortise for the latch, and — critically — install the strike plate with 3-inch screws into the wall stud.
If you're not confident, call a locksmith. The installation cost ($75-$150) is worth it for your front door.
FAQ
What's the best deadbolt for a home front door?
A Grade 1 single-cylinder deadbolt from Schlage, Yale, or Medeco. Look for anti-pick pins, anti-drill plates, and a 1-inch bolt. Install with 3-inch strike plate screws.
How much does a good deadbolt cost?
A Grade 2 deadbolt costs $30-$60. A Grade 1 residential deadbolt costs $80-$200. High-security deadbolts (Medeco, Mul-T-Lock) cost $150-$300+.
Are smart locks as secure as traditional deadbolts?
The best smart locks include a Grade 1 or 2 deadbolt mechanism, so the physical security is comparable. The main risk is battery failure. Choose a smart lock with a key backup.
Should I install a deadbolt myself?
If you're comfortable with a drill and chisel, yes. The critical step is using 3-inch screws on the strike plate into the wall stud. If you're unsure, a locksmith can install it for $75-$150.
