How will this ignition switch improve daily mower use?

What should I expect during installation and maintenance?

Installation is intended to be like-for-like: remove the old switch from the dash, disconnect the wiring harness, and install the Tavaski unit using the existing mounting and connectors. Basic tools are typically sufficient and no special programming is required, since this is a mechanical rotary/key switch rather than an electronic module.

• Uses factory mounting points and standard wiring connections
• No software or ECU reprogramming required
• Inspect wiring and connectors for corrosion before installing

Will the key add security or safety benefits?

Yes — adding a keyed ignition prevents unauthorized starts and can be especially helpful around children or when equipment is stored outdoors. While it’s not a substitute for secured storage, a functional key switch is a simple deterrent and enhances control over who can operate the mower.

• Requires key to turn engine on, reducing accidental startups
• Useful when multiple users share equipment or during storage
• Keyed switch reduces risk of unintentional electrical activation
