No-Drill Smart Locks for Apartments: Best Renter-Friendly Options 2026
How We Test
Every device is installed in a real apartment with no drilling allowed. We live with it for at least two weeks, then remove it and check the wall. We score install ease, removability, portability and whether a landlord would object — then we publish the score, good or bad.
You don't need to replace your lock or drill into your door to get a smart lock. In 2026, several smart locks attach to your existing deadbolt from the inside — no tools, no drilling, no landlord permission.
We tested 8 renter-friendly smart locks and scored each on our Renter Readiness Score (install ease, removability, no-drill, portability, lease compliance).

How No-Drill Smart Locks Work
Instead of replacing your entire lock, these devices attach to the interior side of your existing deadbolt. They grip the thumb turn (the part you twist to lock/unlock) and motorize it. Your exterior key still works normally.
What you need:
- A standard single-cylinder deadbolt (most apartments have this)
- A flat interior thumb turn (not a knob-style)
- Clean door surface for adhesive (if applicable)
What you DON'T need:
- Drilling
- New keys
- Landlord permission (in most cases)
- An electrician

Frequently Asked Questions
Can I install a smart lock in a rental apartment? Yes. No-drill smart locks attach to your existing deadbolt from the inside. They don't modify the lock or door, so landlord permission is typically not required. Always check your lease.
Will a smart lock void my lease? No. No-drill smart locks don't alter the door or lock mechanism. Your exterior key still works normally. The lock is removable with zero trace.
What if my landlord changes the lock? If your landlord replaces the lock, you'll need to recalibrate your smart lock. The adhesive mount works with any standard deadbolt thumb turn.
Can I use a smart lock with a knob (not thumb turn)? Most no-drill smart locks require a flat thumb turn. If your lock has a knob-style turn, you may need a different solution (like a keypad lock that replaces the exterior).
How long do batteries last? SwitchBot: 6-9 months. Wyze: 12 months. August: 3-6 months. Level: 12 months. All use standard batteries (CR123A or AA).
