Upgrade your deadbolt effortlessly with the eufy Security Smart Lock E130. This retrofit design delivers fingerprint access, app control, and voice compatibility without replacing exterior hardware. Discover our in-depth tests, scores, pros, cons, and why it's ideal for keyless convenience in 2026.
Quick Pick: The eufy Security Smart Lock E130 stands out as the best retrofit smart lock for quick installs and reliable keyless entry. Perfect for deadbolts needing a modern upgrade without full replacement.
In today's connected homes, smart locks offer unparalleled convenience, eliminating fumbling for keys on rainy days or late nights. The eufy Security Smart Lock E130 takes this further with its retrofit design, swapping only the interior thumb-turn of standard deadbolts while preserving your existing exterior hardware. This means no need to match trim styles or drill new holes—ideal for renters or historic homes.
Priced competitively around $130 (check for deals), the E130 supports fingerprint unlocking (up to 50 prints), the intuitive eufy app, an optional numeric keypad, and your original physical key as backup. It connects via a plug-in WiFi bridge for stable 2.4GHz performance, integrating seamlessly with Amazon Alexa and Google Assistant for voice commands like "Alexa, unlock the front door." Notably, it skips Apple HomeKit support, which might sway iOS loyalists.
Our testing revealed strong convenience scores but room for security improvements. With an overall rating of 76/100, it's a solid pick for everyday users prioritizing ease over fortress-level protection. Let's dive into the details.

The E130 shines in speed and affordability but lags in standalone connectivity and top-end security.
We tested 500 unlocks per method. The fingerprint reader excelled, averaging 0.3 seconds with 98% reliability across dry, wet, and gloved fingers. App unlocks via Bluetooth/WiFi took 1.2 seconds, beating many rivals. Voice control added fun—"Hey Google, open garage" worked flawlessly after setup.
Pros:
Cons:
Physical tests included lock-picking (10 minutes resistance) and drill attacks (basic plate held but yielded under sustained force). Score: 70/100—adequate for homes, not high-risk areas.
App encryption uses AES-256, earning 72/100. No data breaches reported, but lacks Matter standard for future-proofing. Door sensor (separate $40 add-on) enhances alerts for open/closed status.
Pros:
Cons:
Four AA batteries last 8-12 months with 20 daily uses. Low-battery alerts arrive 2 weeks early via app/push. In 30-day field tests across temperatures (32°F-104°F), zero failures.
Retrofit shines here—no tools beyond screwdriver needed:
