Lawn Mower Key 430 691959 Replacement for Riding Lawnmowers 6 Pack

What It Is

This is a 6-pack of replacement ignition keys (part number 430 691959) designed for riding lawn mowers and garden tractors. They are universal-style keys intended to replace worn, lost, or broken keys on compatible models.

Fitment & Compatibility

Before buying, confirm your mower uses a standard flat-blade ignition key (about 1.5 inches long with a small shoulder). This key is not a transponder or chip key. It directly replaces OEM part 430 691959, commonly found on Craftsman, Husqvarna, Poulan, MTD, and John Deere riding mowers from the 1990s through current models. Check your owner’s manual or existing key for the exact OEM number. If your mower uses a round, tubular, or “safety” key with a plastic head, this will not fit. Measure the blade width (typically 0.125 inches) and length—this key is standard for most single-cylinder riding mowers. For zero-turn mowers or commercial units, verify fitment separately.

Key Things to Know

• Quality: These are basic stamped-metal keys with a plastic grip. They work fine for occasional use but may wear faster than OEM keys if used daily.
• Installation: No tools required—just insert into the ignition switch. If the key doesn’t turn smoothly, check for debris or worn switch contacts.
• Common Gotcha: Some mowers (especially older models) have ignition switches that require a slightly longer or shorter key. Measure your original key’s length before ordering.
• 6-Pack Value: At this price, it’s cheaper than buying a single OEM key. Useful for multiple mowers or as spares.

Should You Buy It

If you need a backup set for a standard riding mower and don’t want to pay OEM prices, this 6-pack is a solid, low-risk buy. Avoid it if your mower uses a security-coded key or a unique shape—stick with the manufacturer’s key in that case. For typical home-use mowers (Craftsman, Husqvarna, MTD, Poulan), this will work fine.
