Steps to Replace Your Key Fob

1. Check Your Coverage

Look for coverage under your car’s warranty, insurance, or roadside assistance.
Some extended warranties and dealers offer key-fob insurance.

Important: Ensure compatibility and call your local mechanic or locksmith before buying.

4. DIY Programming

Instructions are typically in the owner’s manual.
Example:
Chrysler Town & Country (2008): Ordered a $14.30 fob from Amazon and programmed it using the manual.

Lower-Cost Alternatives

1. Locksmith Services

Locksmiths are often cheaper and more convenient than dealers.
Mobile locksmiths can come to your location, saving towing costs.

Honda Pilot (2009): Mobile locksmith cut and programmed a key fob in 15 minutes for $125 (dealer quoted $198).

2. Replacement Shells
