About Product Overview

The KeyStart K043 is a transponder modular head key built for Lexus vehicles that use a sidewinder blade cut. As an advanced security key, it carries the embedded electronic chip your vehicle's ignition system checks for before it'll let the engine start, so a plain cut key won't do the job on these models.

This is the modular head style, meaning the plastic head houses the transponder component separately from the blade, which is common on Lexus high-security key setups. The black plastic head is a double-cut key, and it comes as a single key with no duplicates included.

Because transponder keys have to be programmed to your specific vehicle to actually start it, plan on getting this cut and programmed by a qualified locksmith or dealer after purchase - the key itself is the first step, not the finished product.

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.
