Two different situations bring people to Lista lock questions, and they have opposite answers. If you still have at least one key, you are in the easy case: the key code is printed on it, and spare keys get cut to that code and mailed. If every key is gone, you are in the case this page exists for, and the answer is not a locksmith and not a special tool. It is a ten minute lock swap.
First, identify what you have
Pick up any key that belongs to the cabinet and read it. Standard Lista locks carry a code starting with YNSX plus a number: YNSX05, YNSX-25, and so on. That suffix is your key number, a YNSX-25 lock takes "a 25 key," and cut keys for the standard series are regularly available. Master keyed systems carry their own numbering on the key; if yours does not read YNSX, email a photo of the key to hello@deltaindustrialstorage.com and we will identify the system.
Here is the part that surprises everyone, and it is the single most useful fact on this page: the lock itself shows no number. Not on the face, not on the core. The key number exists in exactly one place, on the keys. Which leads directly to the next section.
Lost every key? Replace the lock. Here is why.
With no key and no number, there is nothing to cut a replacement from, and no amount of squinting at the lock will produce a code that is not there. So skip the dead end: a complete replacement lock, the new core, the gray plastic housing that carries it, and new keys, costs little and swaps in behind the top drawer in about ten minutes. No core release tool, no locksmith visit for the swap itself, no drilling.
One fork in the road first: if the cabinet is locked shut, a local locksmith picks it open without damage, that part is routine, and then you do the swap below. If the cabinet is open, go straight to the swap.
The 10 minute lock swap
Step 1: Order the new lock
Standard replacement locks are on our keys and locks page; email hello@deltaindustrialstorage.com if you want keyed alike locks across several cabinets, which is the natural moment to set that up.
Step 2: Remove the top drawer
Or the top two, depending on how tall your drawers are; you need a hand behind the lock area. Full extension, pull the two captive retaining clips on the rails toward you, lift the drawer up and out. The complete procedure is at drawer removal and repair.
Step 3: Pull the retainer channel
Reach behind the lock on the inside of the cabinet. A U shaped piece of sheet metal locks the core assembly to the cabinet housing. Pull it out toward the right side and the old core drops out easily.
Step 4: Throw the old core away
Without keys it is scrap. No sentiment required.
Step 5: Fit the new lock and slide the channel back
Seat the new core in its gray plastic housing, place the assembly into the cabinet front, and slide the U channel back in to capture it. Cycle the lock with the new key a few times with the drawers still out, then reinstall the drawers.
Step 6: Record the new key number
Photograph the new keys or write the YNSX number down somewhere that is not inside the cabinet. That number is the only record of the code anywhere, and thirty seconds now saves you this entire page next time.
So what is the core release tool actually for?
Rekeying with keys in hand. The release tool lets you pull a core out of its housing from the front, so you can swap cores between cabinets, put a specific key number on a specific bank, or convert an area to keyed alike, all while the housings stay put. It is the right tool when you are reorganizing keys you still have. For the lost key case, it does nothing for you: in the field, roughly nine out of ten lock replacements are the whole lock and housing swap through the retainer channel described above.

Frequently asked questions
How do I know which Lista lock I have?
Read one of your keys. Standard Lista locks carry a code that starts with YNSX followed by a number, like YNSX05 or YNSX-25, and that code is what gets extra keys cut. Master keyed systems use their own numbering; email a photo of the key to hello@deltaindustrialstorage.com and we will identify it. The lock itself shows no number on any of them.
I lost every key to my Lista cabinet. Can a new key be cut?
Not from the lock alone. The key number appears only on the keys, the lock core carries no code, so with every key gone there is nothing to cut from. The fix is faster and cheaper than people expect: replace the lock outright. It is about a ten minute job behind the top drawer, with no special tools, and the new lock arrives with fresh keys.
My cabinet is locked shut and all the keys are gone. What now?
A local locksmith can open the cabinet without damaging it; picking it open is routine and leaves no marks. Once it is open, swap the lock using the retainer channel behind it, about ten minutes, and the cabinet is back in service with keys you control. We quote replacement locks same day at hello@deltaindustrialstorage.com.
Do I need the lock core release tool to replace a lost key lock?
No. The release tool is for rekeying cabinets you still have keys for, swapping cores between cabinets or setting up keyed alike groups while the housing stays in place. A lost key replacement bypasses all of that: pull the retainer channel behind the lock, drop the old core out, and fit the complete new lock.
What comes with a replacement Lista lock?
The complete assembly: a new core, the gray plastic housing that carries it, and new keys. Write the new key number down somewhere that is not inside the cabinet, or photograph the keys, because that number on the keys is the only record of it anywhere.
Can I make all my cabinets open with one key while I am replacing a lock?
Yes, and a lock replacement is the natural moment to do it. Keyed alike locks are ordered to a single code, so a bank of cabinets can come under one key as each lock is swapped. Cores, keys, and keyed alike ordering are all on our keys and locks page at deltaindustrialstorage.com/keys-locks.
