Ignition Key Function

The ignition key works with the mower's ignition switch to control the starting and electrical system.

• Insert the key into the ignition switch
• Turn the ignition switch through its applicable positions
• Activate the mower's electrical system
• Engage the starting circuit when applicable
• Shut down the equipment through the ignition switch
• Remove the key when the equipment is not in use

The key itself does not replace the ignition switch or repair electrical faults elsewhere in the starting system.

Common Reasons for Replacement

Replacement of the 532140403 Ignition Key may be necessary if the original key has:

• Been lost

• Sustained damage around the molded grip
• Become difficult to insert or remove
• Been damaged during equipment operation
• Become unavailable when a spare key is needed

Ignition System Inspection

If installing a replacement key does not restore normal starting operation, inspect other applicable components such as:

• Ignition switch
• Battery
• Battery terminals
• Starter solenoid
• Starter motor
• Fuse
• Wiring harness
• Safety interlock switches
• Brake/clutch switch
• PTO safety switch
• Seat safety switch
• Electrical connectors

A replacement ignition key will not correct a failed ignition switch or another electrical-system problem.

Important Notes

• Verify compatibility with your exact mower model, product number, serial number, and ignition-switch configuration before ordering.
• Match part number 532140403 with the number shown in your equipment's illustrated parts diagram or OEM documentation.
• The alternate formatted number may appear as 532 14 04-03.
• Husqvarna equipment documentation describes this style of component as a molded key.
• This component is an ignition key, not the complete ignition switch.
• Current replacement references state that the key is sold individually.
• Do not assume that the ignition switch, switch nut, wiring harness, starter components, or other electrical parts are included.
• 582920901 is documented as a replacement/cross-reference number associated with this key.
• 140403 is an earlier number replaced by 532140403.
• Do not select an ignition key based solely on its appearance.
• Similar-looking mower keys may use different blade profiles or ignition-switch configurations.
• Never force an incompatible key into the ignition switch.
• If the key does not insert smoothly, verify the part number and inspect the ignition switch for damage or foreign material.
• If the original key broke inside the switch, remove the broken portion before attempting to insert a replacement.
• Inspect the ignition switch if the key feels excessively loose, binds during rotation, or fails to operate the starting system.
• A worn or damaged ignition switch may require separate replacement.
• Installation normally requires no tools; the compatible key simply inserts into the ignition switch.
• Remove the ignition key whenever the mower is unattended, being serviced, or stored.
• Do not leave the key in the ignition during maintenance.
• If the mower does not start after replacing a lost key, troubleshoot the battery, ignition switch, starter circuit, safety interlocks, and related electrical components.
