Understanding how to program your 2003 Toyota Sequoia Key Fob can save you time and money. Whether you’ve purchased a new key fob, or need to reprogram your existing one, this guide provides expert, step-by-step instructions to get you back on the road quickly.

Programming Your 2003 Toyota Sequoia Key Fob Transmitter
The SECUREKEY+ system on your 2003 Toyota Sequoia can support up to four different transmitters. If you need to program new or replacement key fobs, or if you’re looking to add optional features to your existing key fobs, follow these detailed steps. Remember, each step needs to be completed within 15 seconds to avoid the system exiting the programming mode. If this happens, simply restart from the beginning.
