About Product Overview

The ULK640 from KeyStart is a remote head key built for Honda vehicles that use double-cut, advanced security key systems. It combines the physical key blade with the remote transmitter housing in one plastic-head unit, finished in black. If you're replacing a lost key, adding a spare, or setting up a backup for a family driver, this covers the automotive side of high-security key duplication.

Because this is a high-security automotive key, it will need to be cut to match your vehicle's specific key code and may require programming to sync with your Honda's immobilizer system - check with a locksmith or your dealer on programming requirements before you count on it as a working spare. The plastic head keeps it lightweight and easy to distinguish on a ring.

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
