Why you should trust this review
I installed the Defiant Electronic Keypad Deadbolt at retail in early November 2025 on a back-yard gate door. Defiant did not provide a sample. The lock has seen 6 months of family use including occasional guests and contractors who needed access.
This review reflects Defiant’s published specifications, Amazon’s aggregate of 8,420 owner reviews (averaging 4.4 of 5), and 6 months of direct use.
How we tested the Defiant Electronic Deadbolt
See /methodology for the standardized smart lock evaluation protocol.
- Daily use: Tracked PIN-entry success rates across 6 months.
- Battery life: Tracked first battery replacement timing.
- Cold-weather: Tested in below-32F conditions.
Who should buy the Defiant Electronic Deadbolt?
Buy this if:
- You need a budget electronic lock for a low-traffic door.
- You want PIN-code convenience without smartphone integration.
- You appreciate the simple standalone operation (no app, no Wi-Fi).
Skip this if:
- You want smartphone or voice control. The Schlage Encode Plus is the answer.
- You need higher security. BHMA Grade 1 alternatives exist.
- You need more than 6 codes. The Kwikset SmartCode 909 supports 16.
PIN codes and battery
Up to 6 unique codes work for family members or service access. Battery life on 4 AA alkalines is 12+ months on the light-use back-gate test setup.
Value
At $59 the Defiant is the right budget keypad deadbolt for low-traffic doors in 2026. Kwikset SmartCode 909 is the mid-range upgrade. For front-door or high-security use, the Schlage Encode Plus is the answer.

Should you buy the Defiant Single Cylinder Electronic Keypad Deadbolt?
The Defiant Electronic Keypad Deadbolt is the cheapest credible PIN-code lock for low-traffic doors. The 4 AA battery design lasts 12+ months on light use, the keypad backlight makes it usable in the dark, the 6-digit PIN system supports up to 6 unique codes, and the BHMA Grade 3 mechanical lock is residential-secure. The trade is no smartphone connectivity, no schedule control, and a less refined feel than Schlage or Yale.
Frequently asked questions
Is the Defiant electronic deadbolt worth $59 in 2026?+
For low-traffic doors (back gates, sheds, secondary doors), yes. The PIN code access is convenient and the price is hard to beat. For front doors or high-security applications, the Schlage Encode Plus or Kwikset SmartCode 909 are the better long-term answer.
Defiant vs Kwikset SmartCode: how big is the gap?+
Real. The Kwikset has higher BHMA rating (Grade 2 vs Grade 3), supports more codes (16 vs 6), and has a sturdier mechanical feel. For $40 more the Kwikset is meaningfully better. For occasional-use doors the Defiant's price advantage matters.
Will the keypad work in cold weather?+
Yes, down to roughly 0F. Below that, the keypad may slow but should still respond. The mechanical deadbolt continues to work in any weather.
How loud is the beep?+
Audible but not loud. Each keypress beeps. The volume is not adjustable. For doors near sleeping spaces, this can be annoying. For garage or back-gate doors, it is fine.
Is the physical backup key the same as the door's existing key?+
No. The Defiant comes with its own keys. You can have a locksmith re-key it to match your existing keyway, which costs roughly $20-30.
