When you want to make a spare key for a rental, many tenants wonder: "Is it okay to just do it?" The answer is that landlord permission is required before copying a rental key. This article explains why permission is needed, how to copy different key types, where to get copies made, and what to watch out for.
Can You Copy a Rental Key Without Permission?
The property is owned by the landlord. Because tenants are borrowing the property, they need advance permission from the landlord before making a spare key. Most lease agreements also contain rules about key handling.
Why Unauthorized Copying Is a Problem
If an unauthorized spare key causes an incident, the landlord is unable to fulfill their duty to maintain a safe environment. Always consult your landlord or property management company if you need a spare key.
Key Types and Spare Key Difficulty
Disc Cylinder Key
A key with a jagged pattern on both sides, most common in rental properties (especially older buildings). Can be copied at a hardware store or locksmith in minutes. However, the older structure makes it vulnerable to lock-picking.
Dimple Cylinder Key
Common in newer properties built after the 2000s, featuring small circular indentations on the surface. More secure, but requires specialized equipment; copying can take hours to weeks. Often requires ordering from the manufacturer.
Pin Tumbler Key
A traditional key with ridges on one side only. Easily copied at hardware stores or locksmiths in minutes. Watch out for lock-picking risks.
Where to Get Spare Keys Made
Hardware Store
Disc cylinder and pin tumbler keys can usually be copied the same day. Dimple cylinder and electronic keys may not be supported — check in advance.
Professional Locksmith
Many locksmiths have equipment for dimple cylinder keys and can order unusual keys from manufacturers. Mobile service may also be available.
Key Manufacturer
For electronic keys, card keys, and other special keys. More expensive and time-consuming, but essential for keys that cannot be copied elsewhere.
Online Ordering
Send the key's engraved number and manufacturer name and have the copy delivered. Allow several days to weeks for delivery.
Station Kiosks and Handymen
Simple keys may be copied while you wait. However, generalist shops may produce lower-quality copies, so use a specialist for important keys.
Key Precautions
- Always get landlord permission in advance
- Confirm key type and compatible copy locations beforehand
- If using a low-security key, discuss upgrading to a higher-security lock with your landlord
- Manage spare keys carefully and report any loss to the landlord immediately
