How To Start Lexus With Dead Battery

You may quickly start and stop your engine using your regular key fob if your Lexus has an Enform remote and was manufactured in 2020 or later.

If your push-button car won’t start, what should you do?

Your automobile may have a dead battery if your keyless entry system is functional but your engine won’t start. Check the battery voltage with a voltmeter to make sure that this is the issue. The battery needs more voltage to start the automobile if it has less than 12.4 volts.

Can a Lexus be operated without the key fob?

Once the vehicle has been driven, it can be used to move again without a key.

This was revealed to me at the parking garage when the attendant successfully parked my car but was unable to restart it when I returned to retrieve it because the key was in my pocket.

The Lexus keyhole is where?

If the battery in your key fob fails, how does the Lexus key function? For a thorough explanation, view our video below.

It doesn’t happen very frequently, but when it does, not knowing what to do when your key fob won’t function can be really annoying.

If this does occur, don’t worry; there are ways to enter and start your vehicle. Your Lexus key fob has a real, traditional key, and the keyhole is next to the door handle. Once inside, you can start the vehicle by pushing the start button on your key fob.

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.

What should I do if the battery on my key fob dies?

  • On your key fob’s back, search for a little sliding button. You can slide the key fob cover off or click a button to do so. To get it to release, you might need to use your fingernail and a little force.
  • Use the mechanical key to unlock the door after you get it. If your door doesn’t have a key slot, it’s likely concealed beneath the handle cover. To access the key slot, carefully remove the handle cover by using the key.

Now that you’re inside, here’s how to start the car with a dead key fob:

  • Press the START button with the key fob. Instead than pressing the button with your finger as usual, push the key fob against it. Many manufacturers utilize this backup device to make sure the car can start even if the key fob is dead.
  • Check the steering column for a physical key slot if neither of these approaches succeeds (some Mazda models have this feature). To start the car, place the mechanical key within the keyhole.
  • Some vehicles have a secret key fob slot that can be used to start the engine. For instance, the backup slot is located inside the cup holder in some Ford models. Your fob will fit perfectly in the slot. Use the push button start as usual after inserting the dead key fob into the holder.
  • Close the key fob after inserting the mechanical key once more.

What happens if your Lexus key is lost?

Replacement Lexus keys are available at the dealership or with the help of a competent locksmith in your region.

The primary distinction between the two is that a car locksmith will come to you, whereas you must tow your car to the dealer to get a key created there.

Lexus auto keys and fobs are available from local locksmiths, online, or in the parts department of a Lexus dealer near you.
