Getting Your Storage Unit Door Open
Most storage unit doors open with a padlock you bring yourself, a key the facility provides, or a combination lock built into the door frame. The exact method depends on what your rental agreement specifies and what type of lock your unit has. Before you try anything, check your lease paperwork or call the facility — they will tell you which lock system applies to your unit and whether you need to do anything special the first time.
The three most common setups are a personal padlock you install on a hasp, a keyed lock where the facility gives you the key, or a digital/combination lock that the facility controls. Each one opens differently, and using the wrong technique can damage the door or trigger an alarm at some facilities.
Key Takeaways
- Your storage facility will tell you in your lease or rental agreement which type of lock system your unit uses and who provides it.
- If you bring your own padlock, it attaches to a metal hasp on the door frame — do not force it or try to pry the hasp off.
- If the facility provided a key or combination lock, keep it in a safe place because replacement keys and lock resets usually cost money.
- If your key is lost or the lock is jammed, contact the facility office when ready rather than trying to force the door open.
- Digital locks may require you to enter a code or use a mobile app — the facility will show you how during move-in.
Opening a Unit with Your Own Padlock
If your lease says you can bring your own padlock, the door will have a metal hasp — a hinged bracket with a slot — already attached to the frame. You slide the padlock's shackle (the U-shaped part) through the hasp slot and snap it closed. To open it, you reverse the process: unlock the padlock, lift the shackle out of the hasp, and pull the door open.
Make sure your padlock is rated for outdoor use if your unit is outside, because regular indoor padlocks rust quickly and seize up. A padlock that is stuck from rust may not open even with the correct key. When you first install the lock, test it several times to make sure it works smoothly before you leave the unit.
Do not try to pry the hasp off the door frame or force the padlock open if you forget the combination or lose the key. Call the facility instead. Damaging the door or frame will result in repair charges to your account, and the facility has tools to remove locks safely without harming the unit.
Opening a Unit with a Facility-Provided Key
Some facilities install a keyed lock on the door and give you a key during move-in. The lock is usually a standard deadbolt or a lock built into the door handle. Insert the key into the lock cylinder, turn it to the right (clockwise) to unlock, and pull the door open. Turn it to the left (counterclockwise) to lock it again when you leave.
Keep your key in a safe place at home — do not leave it in the unit or hide it near the door. If you lose the key, contact the facility office. Most facilities charge a fee to rekey the lock or issue a replacement key, and the cost varies by facility. Some facilities may require you to wait for a locksmith to come during business hours, which can take a few days.
If the key turns but the door does not open, the lock may be jammed. Do not force it. Call the facility and describe what is happening — they can send someone to check whether the lock is broken or whether something is blocking the door from the inside.
Opening a Unit with a Combination or Digital Lock
Combination locks on storage units usually have a dial or a keypad. If it is a dial, the facility will give you a three-number combination during move-in. Clear the dial by spinning it at least three times to the right, then enter your combination: turn right to the first number, left past the second number and back to it, then right to the third number. Pull up on the shackle to open it.
If the lock has a keypad, enter your code and press Enter or the unlock button. Some facilities use digital locks that connect to a mobile app — you will receive login information during move-in, and you unlock the door through your phone. Write down your combination or save your app login in a password manager, because you will need it every time you visit.
If you forget your combination or your app stops working, contact the facility when ready. Do not try to guess the combination repeatedly — many locks lock you out after several wrong attempts. The facility can reset the lock or provide a new code, though this may take a business day or two.
What to Do If the Door Will Not Open
If you have the correct key, combination, or code but the door still will not open, stop trying. Forcing a stuck door can damage the lock, the door frame, or the door itself, and you will be charged for repairs. Instead, call the facility office and describe exactly what is happening: the lock turns or the code works, but the door does not move.
The problem could be a jammed lock, something blocking the door from inside, ice or dirt around the frame, or a broken door hinge. The facility staff can diagnose the problem and either fix it themselves or send a locksmith. Most facilities respond to access problems within a few hours during business hours.
If you are locked out because you lost your key or forgot your combination, the facility can reset the lock or provide a replacement. This usually takes one to three business days and costs a fee that varies by facility — check your lease for the exact amount.
Preventing Lock and Access Problems
Test your lock or code the first time you visit the unit, before you leave. Do not wait until your next visit to discover the key does not work or you wrote down the combination wrong. If something feels wrong on the first try, call the facility when ready while you are still there.
Keep your key, combination, or app login in a place you will remember. Many people write combinations on a piece of paper and store it at home, not in the unit. If you use a password manager for your app login, make sure you can access it from your phone when you are at the facility.
If you have a padlock, inspect it every few months if your unit is outside. Rust and corrosion can make the lock stick or jam. If the lock is starting to stick, spray it lightly with a silicone-based lubricant (not WD-40, which attracts dirt) and work the key in and out a few times. If it does not improve, replace the lock before it fails completely.
Frequently Asked Questions
What should I do if I lose my key on the way to the storage facility?
Call the facility office and explain what happened. They can provide a replacement key or reset your lock, though there is usually a fee. Ask whether they can meet you at the unit or whether you need to come back another day. Do not try to break into your own unit — it looks like theft and may trigger an alarm.
Can I change the lock on my storage unit?
Check your lease first. Most facilities require you to use their lock or a lock they approve. If you install an unapproved lock, the facility may remove it and charge you for the work. If you want a different lock, ask the facility whether you can replace it with one they approve, and get permission in writing.
What if the combination lock is frozen or stuck from the cold?
Do not force it. Spray the lock lightly with a de-icer product made for locks, wait a few minutes, and try again gently. If it still will not move, call the facility. Forcing a frozen lock can break the internal mechanism, and you will be charged for replacement.
Is there a way to open my unit if I am locked out and the facility is closed?
Most facilities have an emergency contact number for after-hours lockouts. Check your lease or the facility website for this number. Some facilities charge an emergency fee for after-hours access. If there is no emergency number, you will need to wait until the office opens during business hours.
What happens if someone else has a key to my unit?
If you are concerned about security, contact the facility and ask them to rekey your lock or change your code. Most facilities can do this within a business day. You will likely pay a fee for the change. If you suspect someone has broken into your unit, report it to the facility and to local police.
