Put Subaru Key Fob to Sleep: A Comprehensive Guide

Putting your Subaru key fob to sleep can be a valuable tool in preventing theft and extending battery life. This guide will explore various aspects of this process, addressing common questions and concerns, and providing step-by-step instructions.

Understanding the Need to Put Your Subaru Key Fob to Sleep

Why would you want to put your Subaru key fob to sleep? There are two primary reasons: preventing relay attacks and conserving battery power. Relay attacks involve thieves using devices to amplify the signal from your key fob, tricking your car into thinking the key is nearby. Putting the fob to sleep effectively blocks these signals. Additionally, a sleeping key fob consumes significantly less battery power, extending its lifespan.

How to Put a Subaru Key Fob to Sleep: Step-by-Step

Different Subaru models may have slightly different procedures for putting the key fob to sleep. Here are some common methods:

1. The Metal Box Method: Many Subaru models allow you to put the key fob to sleep by placing it in a metal container, such as a cookie tin or a specifically designed Faraday cage. The metal shielding blocks the fob’s radio signals.
2. The Button Sequence Method: Some Subarus have a specific button sequence on the key fob that activates sleep mode. Refer to your owner’s manual for the exact sequence for your model. It usually involves holding down specific buttons simultaneously for a few seconds.
3. The Vehicle Settings Method: In newer Subaru models, you may be able to put individual key fobs to sleep through the car’s infotainment system. Consult your owner’s manual to locate this setting.

Common Issues and Troubleshooting

Sometimes, you might encounter issues when trying to put your Subaru key fob to sleep. Here are some common problems and solutions:

• Key Fob Still Transmitting: Ensure the metal container you’re using is fully enclosed and doesn’t have any gaps. For button sequences, try the sequence again, making sure you hold the buttons for the correct duration.
• Can’t Find the Setting in the Vehicle: Refer to your owner’s manual for the precise location of the key fob sleep setting in your car’s infotainment system.
• Key Fob Won’t Wake Up: Try pressing any button on the key fob. If this doesn’t work, try replacing the key fob battery.

Why Isn’t My Subaru Key Fob Sleeping?

If you’re still having trouble putting your key fob to sleep, there could be a few reasons. A malfunctioning key fob is a possibility. Try using the spare key fob to see if the problem persists. Another possibility is a misinterpretation of the instructions. Carefully reread the owner’s manual, ensuring you’re following the correct procedure.

Benefits of Putting Your Key Fob to Sleep

Aside from the primary benefits of theft prevention and battery conservation, putting your Subaru key fob to sleep provides peace of mind. Knowing your vehicle is secure from relay attacks offers a sense of security. The extended battery life also saves you the cost and hassle of frequent replacements.

How Long Does a Subaru Key Fob Battery Last?

Typically, a Subaru key fob battery lasts between 3-5 years. Putting your key fob to sleep when not in use can significantly extend this lifespan.

Can I Program My Own Subaru Key Fob?

While some basic programming tasks can be performed at home, more complex procedures like programming a new key often require specialized equipment and professional assistance.

Conclusion

Putting your Subaru key fob to sleep is a simple yet effective way to enhance security and prolong battery life. By understanding the methods and troubleshooting any potential issues, you can ensure the continued protection of your vehicle. Remember to consult your owner’s manual for specific instructions related to your Subaru model. Put your Subaru key fob to sleep today for enhanced security and peace of mind.
