Our recommended solution
Important Details
Looking for a remote starter for your 2003-2009 Lexus GX? The GX 470 is a key-start vehicle, and we carry compatible options for it, with the Fortin EVO-ONE as our recommended pick. This installation is hardwired rather than plug-and-play, rated 4 out of 5 for difficulty (hard) — there is no plug-in T-harness made for this generation of GX.
Good news on the keys. The GX 470 has a factory engine immobilizer, so the remote starter needs a bypass to crank the engine. On a lot of Toyota-family trucks from this era that means a spare key gets permanently committed to a bypass box hidden in the dash. Not here — Fortin's solution for this vehicle is a no-key-sacrificed bypass. One original key has to be present at the time of programming, but it goes home in your pocket.
A key fob kit is required, as 3x-lock activation from your factory remote isn't supported on this vehicle, on any of the solutions we carry.
If you have a 2010 or newer GX, it's a push-button-start vehicle and the install is a different job — see our 2010-2019 GX page instead. Lockdown Security has been installing remote starters across Toronto and the GTA since 2003, with worldwide shipping available for DIY customers throughout Canada. All Lockdown Security remote starter installations include a lifetime installation warranty.

Vehicle-specific harnesses for this vehicle. A harness is not a remote starter on its own — it has no electronics and must be paired with a compatible control module.
⭕ means the solution needs a programming tool to finish the install.
🔑 means one of your keys stays permanently in the vehicle.
❗ means your factory fob can't trigger the starter, so you'll need a remote kit on top.
Install difficulty runs 1 to 5.
A 1 or 2 is realistic if you're comfortable with vehicle wiring.
A 4 or 5 we'd recommend having done.
Three to four hours, same day, at our Markham shop. Every installation carries a lifetime warranty on our work, and we've been doing this since 2003.
Three to four hours for most vehicles, done the same day at our Markham shop. Harder vehicles take longer, and we tell you that before you book rather than after. Every installation carries our lifetime warranty on the work.
No. Where a harness exists we connect through your vehicle's factory connectors rather than cutting into the loom. A manufacturer can only refuse a claim if they can show the installation caused the fault, and a properly fitted remote starter doesn't give them that.
It depends how you trigger it. Your factory key fob reaches 150 to 500 feet at best, line of sight. A dedicated remote kit reaches considerably further, up to three miles on the longest-range options. A smartphone controller has no range limit at all.
Yes, by adding a smartphone controller. Range stops mattering entirely. There is an ongoing plan cost, which we set out plainly on that page rather than leaving you to find it at checkout.
Plenty of our customers do. Check the install difficulty on the solution you're looking at — a 1 or 2 is realistic if you're comfortable with vehicle wiring, a 4 or 5 we'd recommend having done. Everything ships pre-programmed for your vehicle, and our technicians will take your call while you're under the dash.
A remote starter can be removed and refitted to another vehicle, but it usually needs a different harness and bypass for the new car. Tell us both vehicles and we'll say honestly whether moving it is worth it against the cost of the parts.
Tell us your year, make, model and trim and we'll confirm what fits before you order.
