Do Storage Units Require You to Buy Their Lock? (2026 Guide)

The simple answer

Sometimes, yes. Many storage facilities require renters to use a specific type of lock, and some facilities strongly push customers to buy that lock on-site during move-in.That means a storage unit that looks cheap online can end up costing more on day one once the required lock is added.

Why storage facilities sell locks

Storage facilities often sell locks because it makes move-in easier, gives them more control over the lock type being used, and creates another source of revenue.Some facilities may require a cylinder lock for indoor hallway units, while others may allow a standard padlock for outdoor drive-up units.

What kinds of locks storage facilities use

The lock type depends on the facility and the door style.• Common options include:• Standard padlocks• Disc locks• Cylinder locks• Electronic keypad systems at some newer facilities

When a facility may require its own lock

Some storage companies require you to buy a lock directly from them at move-in, especially if the unit uses a lock style that doesn’t fit standard hardware.Other facilities allow you to bring your own lock as long as it fits the unit correctly and meets their security requirements.

How much storage locks usually cost

Storage facility lock prices often range from about $10 to $25, though some specialty locks may cost more.This may not seem like a huge amount, but it still increases the real move-in cost of the unit.

Why this matters when comparing storage prices

Most renters compare storage units based on the advertised monthly rent, but the real first-month cost can include:• Admin fees• Insurance• Deposits• Lock purchases• Taxes in some areas• That’s why a low promo price doesn’t always mean the facility is cheaper.

What to ask before move-in

Before renting, ask:• Do I need to buy your lock?• Can I bring my own lock?• What type of lock fits this unit?• How much does your lock cost?• Is the lock included in any move-in fee?

The bigger pricing issue

A required lock is usually a small cost compared to future price increases, but it’s still part of the total amount renters should compare before signing.The smartest comparison is always:move-in cost + monthly cost + long-term price increase risk
