USARemote Lexus Key Fob Set HYQ1512V replacement for 1997–2005 ES300 GS300 GS400 GS430 IS300 LS400 — Set of 2, ready-to-program wi

USARemote replacement key fob set (HYQ1512V) restores keyless entry for compatible 1997–2005 Lexus models and arrives as a complete electronic assembly with battery.

If your Lexus remote stopped working or you need a spare, this pair of aftermarket key fobs is made to match the original HYQ1512V / 89785-50031 specifications for ES300, GS300, GS400, GS430, IS300, and LS400 model years 1997 through 2005. Each unit ships with the circuit board and pre-installed battery, so once programmed they behave like factory remotes for locking, unlocking, and trunk release where supported. These are aftermarket replacements manufactured to be compatible with OEM function, not original dealer parts.

Will these key fobs work with my 1999 Lexus GS300?

Yes — this set is designed to fit Lexus ES300, GS300, GS400, GS430, IS300, and LS400 from 1997 to 2005 that use the HYQ1512V remote protocol. Compatibility depends on the original part number and vehicle receiver; check the current remote’s part number (HYQ1512V / 89785-50031) or your owner manual to confirm match.

• Compatible models: ES300, GS300, GS400, GS430, IS300, LS400 (1997–2005)
• Replacement for part numbers: HYQ1512V and 89785-50031
• Sold as a set of 2 remotes for spares or multi-driver households
• Aftermarket replacement — not OEM dealer-branded

How do I program these remotes to my Lexus?

Programming normally requires access to one master key already programmed to the vehicle. If you have that master key, you can follow the vehicle’s on-board procedure to self-program the new fobs; otherwise a locksmith or dealer will be needed to complete programming.

• Self-programming: one working master key required
• No master key: professional programming by locksmith/dealer is necessary
• Each remote ships with battery and full electronic assembly ready for programming
• Instructions vary by model year — consult your owner manual or technician

What do I get in the box and are batteries included?

Each purchase includes two complete keyless entry remotes with the electronic circuit board and battery preinstalled. Because the fobs are complete assemblies, there’s no soldering or parts swapping required — once the remote is programmed, it should function like the original keyless unit.

• Set of 2 aftermarket key fobs (HYQ1512V-compatible)
• Complete electronic assemblies with batteries already installed
• No separate components or solder work needed
• Ships ready for vehicle programming

Are these new, and how do they compare to dealer remotes?

These are aftermarket replacement remotes manufactured new for compatibility with the listed Lexus models. They offer the same basic remote functions at typically lower cost than dealer-branded OEM units; however, dealer remotes may carry manufacturer warranty or branding that aftermarket parts do not.

• Aftermarket — built to match HYQ1512V functionality
• Cost-effective alternative to dealer remotes
• Includes electronics and battery, ready for programming
• No dealer programming included if a master key is unavailable

Who this is for: this USARemote key fob set is ideal for owners of compatible Lexus ES300, GS300, GS400, GS430, IS300, or LS400 vehicles (1997–2005) who need a backup remote, a replacement for a lost or damaged keyless entry remote, or an affordable spare set for multiple drivers. Choose this kit if you can program with an existing master key or can access professional programming services; it’s not a match if you require factory-branded remotes or dealer enrollment services.
