When Your Lexus Smart Key Fails

The Smart Key is an ultra-convenient feature that lets you lock and unlock your 2021 Lexus IS, open the trunk, and start it without ever taking it from your pocket. However there comes a point when the battery for the key fob dies.

You can, fortunately, replace the battery yourself by using an flathead screwdriver and lithium battery CR2032 (available at most electronics stores and hardware stores). Here's how to do it!

Keyless Entry

Your Lexus key fob contains hardware that connects to the sensors in your vehicle. This lets you lock and unlock your doors and trunk, as well as open it and also start the ignition push-button. This is an amazing convenience that makes driving in a Lexus an absolute blast than it would be in a traditional car. However, the key fob will eventually need batteries replaced in order to work properly.

The good news is that you can prolong the life of your key fob battery by keeping it at a minimum of three feet away from electrical appliances that generate magnetic fields, including TVs, cell phones and battery chargers, induction cookers and table lamps. The closer your key fob is to these devices the more power they will use.

Immobilizer System

When you put your key in the ignition, it sends an ID code to the receiver inside the car. If the ID code matches that in its memory, then the car's computer will let the engine start. But if the ID code isn't compatible, it triggers an immobilizer that prevents the engine from starting.

This technology isn't 100% secure but it works even in the event you lose your keys. It is possible to "hack" an anti-theft system that uses radio waves. A thief could use an aerial antenna to detect the signal and spoof it into telling the car that the key is in.

To overcome this, experts are working on safer systems. Some systems offer WiFi connectivity un-detectable installations, as well as pin code entry through buttons on the dashboard. Thatcham Research has developed a system of grading and approbation to assist buyers in comparing products.

A quick check of the owner's manual will aid you in locating the correct replacement. Fuses are another potential culprit and should be checked regularly. If one blows up, the replacement can be purchased from an auto parts store.

Key Blade

The key fob also has components that allow communication with your car's Smart Access system and push-button start. Your key fob could be designed to last for an extended time, but the constant use and exposure of weather elements can cause your key to fail sooner than you expected.
