Will a dead key fob prevent a car from starting?
A keyless entry system won’t start the engine until it detects that your key fob is inside the car. The system probably won’t be able to tell when the key fob is inside the car if it has a dead battery, which will prevent the engine from starting. By pressing down while placing the fob on the start engine button, you can get past this problem. Even though this should enable your engine to start, it is still beneficial to change the fob batteries whenever you have the opportunity.

Starting the car
Your key fob or a mobile device can both be used to remotely start your Lexus RX 350. In both cases, your RX 350 will operate for 10 minutes and then turn off on its own if no activity is seen during that time.
Key fob
Within 2 seconds, press the LOCK button on your key fob twice. To make things simpler, imagine this as a double-click.
When you successfully finish these two stages, your engine should start and your turn hazards should flash.
Mobile device
The mobile device option entails installing the Lexus app, setting up your account, and configuring your vehicle, which makes it initially more difficult to use Lexus’ Enform Remote service. However, you need just finish steps 1-3 the first time you remote start your Lexus RX 350 using a mobile device.
Get the Lexus app for your smartphone by visiting the Apple Store or Google Play.
Verify your location and language in the Lexus app, then select SIGN-IN or MAKE AN ACCOUNT.
Enform Remote service for your RX 350 can be activated by entering it into the Lexus app.
The end! Your Lexus RX 350 engine should start, and your warning lights should flash.
Turning off the engine
It’s just as easy to remotely turn off the engine of your Lexus RX 350 as it is to start it up, and there are two methods to accomplish it: with your key fob or with a mobile device.
To remotely turn off the engine of your Lexus RX 350, press and hold the LOCK button on your key fob for at least two seconds. We normally advocate this method as the most secure one because it keeps your car doors secured, in contrast to the next technique we’ll discuss.
You can also hit the UNLOCK button on your key fob as an alternative. This will lock your car’s doors and switch off the engine. Your doors will quickly lock again if no activity is detected.

When your key fob indicates a low battery, how long do you have?
A normal key fob with a low battery can last up to 4 to 6 years, whereas a smart key fob with a low battery can last for up to 2 to 3 years. This is what? Since nothing lasts forever, it makes sense to be aware of the time limit set for each equipment you have in your possession.
