If you're wondering how to get your 2013 lexus es 350 remote start working, you aren't alone, as the system can be a bit finicky depending on which setup your car actually has. It's one of those features that feels like a total luxury until it suddenly stops responding, leaving you to step into a freezing cabin in the winter or a literal oven in the middle of July.
The 2013 model year was an interesting one for Lexus. It was the first year of the sixth generation ES, and while it brought a lot of modern tech to the table, the remote start situation has become a bit of a headache for second and third owners. Whether you're trying to figure out if your car even has the feature or you're looking to install something better, there's a lot to unpack.
Did My Car Come With Remote Start?
The most common question people ask is whether their car even has this feature from the factory. Back in 2013, Lexus offered a system called Lexus Enform with Safety Connect. If your car was equipped with this, it technically had remote start capabilities.
However, there's a massive catch that catches people off guard. The factory remote start for a 2013 Lexus ES 350 was subscription-based. Even if the hardware is in the car, Lexus designed it so that the remote start functionality was tied to their Enform service. If you aren't paying the yearly fee, the button presses on your remote might do absolutely nothing.
To make matters worse, there was a "3G Sunset" a couple of years ago. Since the 2013 models relied on older cellular technology for their connected services, Lexus actually discontinued the Enform service for these older vehicles. This means that for many owners, the factory-installed app-based remote start is officially dead and gone. It's frustrating, but it's the reality of how tech ages in cars.
The Secret Key Fob Sequence
Before you go out and spend money on a new system, you should try the "secret" key fob sequence. Even if the app-based service is dead, some 2013 ES 350s have a localized remote start that works directly via the radio frequency of the key fob.
Here is how you test it: 1. Press the Lock button on your Lexus remote. 2. Press the Lock button a second time within one second. 3. Press and hold the Lock button for about three seconds.
If it works, you'll see the hazard lights flash, and after a few moments, the engine should crank up. If you try this five times and nothing happens, your car likely doesn't have the internal Res (Remote Engine Starter) module installed, or it was one of the versions that strictly required an active Enform subscription to function.
Why Does the Engine Turn Off When I Open the Door?
If you actually get your 2013 lexus es 350 remote start to work, you'll quickly notice something that drives almost every Lexus owner crazy: the engine shuts off the moment you pull the door handle.
You'll see people complaining about this on every Lexus forum on the internet. You remote start the car, let it warm up for ten minutes, walk out to the driveway, open the door, and click—the engine dies. You then have to get in and start it all over again.
Lexus claims this is a "safety and anti-theft" feature. They don't want someone smashing your window and driving off with the car while the engine is running. While other brands have figured out how to keep the engine running while requiring a key presence to shift out of park, Lexus stuck to their guns on this one for years. It's annoying, but it's normal behavior for the factory system.
Moving to an Aftermarket Solution
Since the factory system is either defunct due to the 3G sunset or just plain annoying because of the door-open shutoff, most 2013 ES 350 owners eventually look toward aftermarket options. Honestly, this is usually the better move anyway.
Modern aftermarket kits are incredibly sophisticated. You can get "plug-and-play" kits that don't require you to hack into your car's wiring harness. These kits usually sit between your car's computer and the factory wiring. They can often be programmed to work with your original Lexus key fob (usually using that same "Lock-Lock-Hold" sequence), or they can come with their own long-range remotes.
The best part about some of these aftermarket kits is that you can sometimes bypass that annoying engine shutoff. Some kits allow for a "key takeover" procedure, though it's worth noting that the 2013 ES 350 with its push-to-start system is notoriously difficult to configure for takeover. Most installers will tell you that even with an aftermarket kit, the engine is probably still going to shut off when you open the door.
Is DIY Installation Possible?
If you're a bit handy and don't mind crawling under your dashboard, you can definitely install a 2013 lexus es 350 remote start kit yourself. There are companies like 12Volt Solutions or MPC that sell kits specifically flashed for the ES 350.
These kits usually involve: * Removing the paneling under the steering wheel. * Unplugging a couple of factory connectors. * Plugging in the "T-Harness" from the kit. * Mounting a small control module. * Running a simple programming sequence.
It's way less intimidating than it sounds. You aren't cutting wires or soldering anything; you're basically just adding a bridge between existing plugs. If you can put together IKEA furniture, you can probably handle a T-harness remote start install.
Common Troubleshooting Tips
If you have a remote start system installed but it's being grumpy, there are a few things that will prevent the car from starting. Lexus (and most aftermarket brands) built in several "safety cancels" that stop the remote start from firing up.
- The Check Engine Light: If your car has a CEL on for any reason—even something silly like a loose gas cap—the remote start will not work. The car's computer decides that if there's an engine issue, it shouldn't be running unattended.
- Low Battery: If your car battery is getting weak, the system might have enough juice to turn on the lights but not enough to feel "confident" in a remote start. Similarly, if your key fob battery is low, the signal might not be strong enough to complete the "Hold" part of the sequence.
- Open Hood or Doors: There is a pin switch under the hood. If that switch is broken or if the hood isn't latched perfectly, the car thinks you're working on the engine and won't let it start remotely for safety reasons.
- Fuel Level: If your gas light is on, the remote start usually won't engage. It's the car's way of making sure you don't run out of gas while it's idling in your driveway.
The Cost Factor
If you decide to go the professional route, you're probably looking at anywhere from $300 to $600 for a solid 2013 lexus es 350 remote start setup. The price varies depending on whether you want a basic kit that uses your factory remote or a high-end system with an app that lets you start your car from a different state.
To be honest, the basic kit is usually plenty for most people. The factory Lexus remotes have decent range, and unless you work in a massive office building where your car is parked three blocks away, you probably don't need the fancy cellular-linked systems.
Final Thoughts on the ES 350 System
At the end of the day, having a remote start on a 2013 Lexus ES 350 makes a world of difference in the overall ownership experience. These cars are known for their comfort and longevity, and adding a reliable way to pre-condition the cabin temperature just adds to that "luxury" feel.
It sucks that the original Lexus Enform system is essentially a brick now because of the cellular network changes, but the aftermarket has stepped up in a big way. If your "Lock-Lock-Hold" trick doesn't work, don't sweat it. Grab a plug-and-play kit, spend an hour on a Saturday morning installing it, and you'll be back to enjoying a warm car by the time the first snow hits. It's one of those small upgrades that you'll appreciate every single morning.
