Lost Your Craftsman Mower Key? Replacement Options Compared

Craftsman riding mowers and lawn tractors have used a handful of simple ignition keys for years, and losing one is one of the most common reasons a perfectly good mower sits idle in the garage. The good news is that a Craftsman lawnmower key is usually cheap and easy to replace, as long as you match the right part number. Most keys sold online are not made by Craftsman at all. They are aftermarket keys built by other companies to fit Craftsman ignition switches, and in this guide we say plainly which ones are which.
The six options here differ in who made them and which key shape they copy: two Strongthium packs match the common 140403 key, one pack matches the 925-2054A key, one fits the Craftsman V20 battery mower, one is a seven-key assortment for guessing, and one is a genuine original equipment key with part number 532140403.

Strongthium 140403 GY20680 Replacement Ignition Keys
Best for: Riding mowers using key 140403 or 411932
Pros
- Two keys plus heavy-duty ring
- Lists Craftsman 140403 and 411932
- Also matches AYP 532140403
Cons
- Aftermarket, not a Craftsman part
- Check photos before ordering
The Strongthium 140403 GY20680 Replacement Ignition Keys are aftermarket keys, meaning they are made by a third party to fit, not by Craftsman. The listing names Craftsman part numbers 140403 and 411932 among its matches, along with AYP 140401, 140402, 140403, 532140401 and 532140403. AYP is the parts system used on many older Craftsman tractors, which is why that number shows up so often on Craftsman ignition switches.
The package includes 2 replacement ignition keys and 1 heavy-duty key ring. The keys measure about 2.55 x 1.06 x 0.19 inches. The listing says it suits lawn tractors, riding mowers and zero turn mowers from several brands, and it asks buyers to check the product images before ordering. That is good advice: compare the shape of the key head and blade in the photos with your ignition slot.
This pack suits the owner of an older Craftsman riding mower who knows the key is the 140403 style and wants one to use and one to hide. If you want more spares, the 4-pack version below gives you extra keys.

feishunteng 5PCS 625-05000 625-05002 925-2054A Replacement Ignition Keys – Compatible with Cub Cadet, MTD, Troy-Bilt, and Craftsman Lawn Mowers Replacement for 925-1745A, 725-1745, 725-2054
Price and specifications are read from the Amazon product page and can change.
5PCS 625-05000 625-05002 925-2054A Replacement Ignition
Best for: Tractors needing key 925-2054A
Pros
- Five keys in one pack
- Covers 925-2054A and 925-1745A
- Long list of matching part numbers
Cons
- Aftermarket, not a Craftsman part
- No Craftsman models named
The 5PCS 625-05000 625-05002 925-2054A Replacement Ignition key pack targets a different key shape, often called the 925-2054A ignition key. The listing matches a long list of part numbers: 925-2054A, 925-1745A, 925-1745, 625-05000, 625-05002, 725-1744, 725-1744A, 725-1745, 725-1745A, 725-2054 and 725-2054A. These are aftermarket keys, not Craftsman parts.
The title says they are compatible with Craftsman lawn mowers, but the detailed model lists only name tractors from other brands built between 2003 and 2009, and no specific Craftsman model numbers. So the safest way to use this pack is to match the part number printed in your manual or parts diagram, not your mower’s brand. You get 5 metal keys and a key ring.
This suits Craftsman owners whose manual lists 925-2054A or one of its related numbers. If your key is the 140403 style, the Strongthium packs are the right match instead.
Mower Safety Key Replacement for Craftsman V20 Battery Mowers

KAIERSUGT Mower Safety Key Relacement Fit for Craft-sman V20 Mower, CMCMWSP220P2 Model
Price and specifications are read from the Amazon product page and can change.
Mower Safety Key Relacement Fit
Best for: Craftsman V20 CMCMWSP220P2 owners
Pros
- Made for one specific model
- Tiny, simple plug-in key
Cons
- Aftermarket, not a Craftsman part
- Fits only the named V20 mower
The Mower Safety Key Relacement Fit for Craftsman V20 is a different kind of key altogether. Battery push mowers do not have an ignition switch. Instead, they use a small safety key that must be inserted before the motor will run, which keeps children from starting the mower. This aftermarket key is listed for the Craftsman V20 mower model CMCMWSP220P2.
It is tiny at 1.18 x 1.18 x 0.18 inches and weighs 0.634 ounces. The listing describes simple installation and a robust, compact structure, but it gives no detail on the material. It fits one named model, so check the model number on your mower’s label before ordering.
This is only for owners of that specific V20 mower. Riding mower owners should look at the ignition key packs instead.
Strongthium 4PCS 140403 GY20680 Replacement Key for Extra Spares
Strongthium
Strongthium 4PCS 140403 GY20680 Replacement Key
Price and specifications are read from the Amazon product page and can change.
Strongthium 4PCS 140403 GY20680 Replacement Key
Best for: Households wanting several 140403 spares
Pros
- Four keys with key chain
- Same 140403 compatibility list
- Spares for every family member
Cons
- Aftermarket, not a Craftsman part
- Check photos before ordering
The Strongthium 4PCS 140403 GY20680 Replacement Key set shares the same compatibility list as the 2-key Strongthium pack, including Craftsman 140403 and 411932 and AYP 532140403. It is also aftermarket and made by the same manufacturer listed for the 2-pack.
The difference is quantity: 4 keys with a key chain in a nylon package. The listing again asks you to check the product images to confirm the right part.
This suits families where several people mow, or anyone who keeps losing keys in the grass. For a single spare, the 2-pack is enough.
7-Pack Lawn Mower Ignition Key for Unsure Owners
Best for: Owners unsure of their key type
Pros
- Seven different key profiles
- Covers GY20680 and 925-2054A
- All keys on one ring
Cons
- Aftermarket assortment
- Unused keys you may not need
The 7-Pack Lawn Mower Ignition Key set takes a different approach: seven different key types on one ring. The listing says it matches common part numbers including GY20680 and 925-2054A, the two Craftsman-related key styles covered above, plus several others. It is aftermarket, and it lists Craftsman among many compatible brands.
It covers walk-behind mowers, riding mowers, garden tractors and utility tractors that use matching key profiles.
This suits someone who bought a used mower with no key and no manual. For a known part number, a targeted pack is simpler.
AYP 532140403 Lawn Mower Ignition Key for Genuine OEM Fit
Best for: Owners wanting a genuine OEM key
Pros
- Listed as genuine OEM part
- Part number 532140403
Cons
- Single key, bulk packed
- Spec sheet lists switch data
The AYP 532140403 Lawn Mower Ignition Key is the only option here listed as a genuine part. The description calls it a Craftsman 532140403 genuine original equipment manufacturer (OEM) part, new and bulk packed. The listing also calls it a genuine part for another brand that shares this part number, which is common with AYP parts.
Its specifications describe an ignition switch rather than a key, with terminals and mounting type, so we would ignore those details. The listing tells you to consult your owner’s manual and does not say how many keys come in the bag.
This suits owners who want factory fit on a 532140403 tractor. The Strongthium packs match the same number with more keys.
How to Choose the Right Craftsman Lawn Mower Key
Find your part number first. Look in the owner’s manual, the parts list or a parts diagram for the ignition switch. If you see 140403, 411932 or 532140403, the Strongthium packs and the AYP key are the matches. If you see 925-2054A or a 725-1745 style number, the 5-pack is the match. If you are already looking up parts for your tractor, our Craftsman 42-inch mower deck guide shows how model numbers are listed.
Next, decide between genuine and aftermarket. Only the AYP 532140403 key is listed as OEM. Aftermarket keys are generally simple copies and are sold in multi-packs.
Consider mower type. A battery push mower like the Craftsman V20 uses a safety key, not an ignition key.
When stuck, buy the assortment. The 7-pack lets you try several profiles. While you are doing maintenance, our Craftsman 42-inch blade guide is a helpful next step.
