Is your 2011 Scion xB key fob not working as it should? Perhaps you’ve added a new remote, or maybe you’re experiencing issues with the existing one. Understanding how to program your key fob can save you a trip to the dealership and get you back in control of your vehicle’s keyless entry system. This guide provides step-by-step instructions on programming your 2011 Scion xB key fob, ensuring you can manage your vehicle’s remote functions effectively.
Before we dive into programming, it’s worth noting that while this guide focuses on the remote programming aspect, the physical key portion of your Scion xB key fob needs to be cut and programmed by a professional locksmith. This article will cover the remote programming procedures.
There are four distinct modes available for programming the remote door lock functions on your 2011 Scion xB. These modes cater to different needs, whether you’re checking the number of programmed remotes, adding a new one, rewriting all existing ones, or even disabling the remote function altogether. Let’s explore each mode in detail.
Understanding the Programming Modes
- Confirmation Mode: This mode is useful for checking how many remotes are currently programmed to your vehicle. It’s a simple way to verify if any remotes are already recognized by your Scion xB.
- Add Mode: Use this mode when you want to add a new key fob without erasing any previously programmed remotes. This is ideal when you get a new remote and want to integrate it with your car’s system alongside your existing fobs.
- Rewrite Mode: When you need to replace all existing remotes with new ones, Rewrite mode is the option to choose. This will erase all previously programmed remotes and allow you to program a fresh set.
- Prohibition Mode: This mode is for disabling the remote door lock function entirely and erasing all programmed remotes. It might be used for security reasons or if you prefer to only use the physical key.
Step-by-Step Programming Instructions
Ensure you follow these instructions carefully. It’s crucial to adhere to the timings and sequences for successful programming. For all modes, start with the key removed from the ignition, the driver’s door open, and the doors unlocked.
