Understanding Key Fob Programming for Your 2003 Impala

Understanding the different types of key fobs and the potential issues you might encounter is crucial for successful programming.

Types of Key Fobs for a 2003 Impala

The 2003 Impala generally uses two types of key fobs: the basic remote entry fob and the key fob with integrated key. Knowing which type you have will help you choose the correct programming procedure.

• Basic Remote Entry Fob: This fob solely controls locking and unlocking.
• Integrated Key Fob: This combines the remote functions with the physical ignition key.

Before starting, ensure you have all necessary materials, including your working key fob(s) and a copy of your owner’s manual, which often contains model-specific instructions.
