Works With
A solid retrofit smart lock with fingerprint access best suited for users wanting to keep their existing deadbolt but less ideal for those needing physical key backup or broad smart home integration.
The Yale Smart Lock Conversion Kit is designed to retrofit your existing deadbolt, allowing you to keep your original keys while adding Wi-Fi and fingerprint keypad access. This is a solid choice if you want to upgrade your door security without replacing the entire lock mechanism. The fingerprint sensor is a convenient touch for quick entry, and the Wi-Fi connectivity means you can control access remotely without needing a separate hub. However, the lock's ecosystem integration is somewhat limited compared to competitors like August Wi-Fi Smart Lock or Schlage Encode, which offer broader smart home compatibility. Setup typically takes around 20-30 minutes but can be tricky if your deadbolt isn’t standard size or if you’re not comfortable with minor mechanical adjustments. The keypad and fingerprint scanner work well but can occasionally have delays or require multiple scans, especially in low light or wet conditions. Battery life is decent, usually lasting several months on a set of AA batteries, but the lock lacks a physical key override in case of battery failure, which could be a real inconvenience. This lock is perfect for users who want to maintain their existing deadbolt hardware and prefer a fingerprint option without investing in a full smart lock replacement. It’s less ideal for those who want deep smart home integration or who need a lock with a physical key backup. Overall, it’s a good mid-range option with some trade-offs in flexibility and ecosystem support.

Ecosystem
Let Yale welcome you home with it’s very first retrofit biometric smart lock: the Yale Approach Lock with Wi-Fi + Keypad. This discreet, interior-only lock installs over your existing deadbolt and lets you keep your keys, while the keypad can be placed anywhere within Bluetooth(R) range- so you're effortlessly enhancing your door without changing a thing about it. Thanks to the biometric keypad, enjoy an extra layer of convenience and security and enter your home with just a simple touch of your finger. With multiple ways to lock your door- including Auto-Lock with Doorsense and One-Touch Locking, and the ability to easily track who comes and goes using the Yale Access App, rest easy knowing your home is secure at all times.
Connectivity
No voice assistant support; full features require Yale Access app; limited regional availability (US and Canada only).
Compared to the August Wi-Fi Smart Lock, Yale’s kit keeps your existing deadbolt, which August does not, but August offers better integration with Alexa, Google Assistant, and Apple HomeKit. The Schlage Encode provides a built-in keypad and Wi-Fi with a physical key backup, which Yale’s kit lacks. Meanwhile, the Ultraloq UL3 BT offers fingerprint access plus a mechanical key, but requires Bluetooth rather than Wi-Fi for remote control. Yale is a middle ground: good for retrofit and fingerprint access but with fewer smart home features and no key backup.
Installation rates around a 3 out of 5 in difficulty. It typically takes 20-30 minutes for someone moderately handy. You’ll need a screwdriver and possibly a drill if your deadbolt doesn’t fit perfectly. The kit is designed to work with most standard deadbolts, but non-standard sizes can cause issues. Professional installation isn’t usually necessary unless you’re uncomfortable with minor adjustments or troubleshooting alignment.
Users report generally reliable daily performance, with the fingerprint scanner working well most of the time but occasionally requiring multiple attempts, especially with wet or dirty fingers. The app is straightforward but somewhat basic, lacking advanced notifications or detailed access logs. Response time for remote unlocking is typically under 5 seconds. Battery life is solid, lasting several months on AA batteries, but the absence of a physical key backup raises concerns if batteries die unexpectedly.

Homeowners looking for a secure, convenient locking solution that integrates with smart home systems.
Consider if you need integration with Alexa or Google; otherwise, it's a solid choice for smart locking.
Buy this lock if you want to keep your existing deadbolt and add fingerprint access without a full replacement. Pair it with a smart home hub if you want better ecosystem integration, though it works standalone. Avoid if you need physical key backup or advanced app features. Check your deadbolt size before purchasing to ensure compatibility and plan for a 20-30 minute installation.
