2008 Dodge Magnum Key Fob Programming
Updated 2026 Programming, battery & replacement fob
You can program a 2008 Dodge Magnum key fob yourself in a few minutes using a working key or remote, no dealer visit needed. Follow the steps below, then check the battery and the correct replacement fob (with FCC ID and part number) if you need a new one.
On these Chrysler, Dodge, and Jeep vehicles you can add a new key yourself if you already have two working keys. Vehicles from 2010 and newer must be done by an automotive locksmith or dealer.
Before you start
- Two working (programmed) keys
- Your new key, already cut
- 1Insert the first programmed key and turn the ignition to ON. Wait about 3 seconds, turn OFF, and remove the key.
- 2Within 15 seconds, insert the second programmed key and turn to ON. After about 10 seconds the immobilizer warning light comes on and you'll hear a tone. Turn OFF and remove the key.
- 3Within 50 seconds, insert the new key and turn to ON. After about 10 seconds you'll hear a tone and the immobilizer light stays on for 3 seconds — programming is complete.
- 4To add more keys, repeat from step 1 for each one.
Tips & troubleshooting
- If your vehicle had an ignition recall performed, DIY programming won't be available.
- Some 2009-and-newer Dodge Ram trucks need dealer programming — check with your dealer if you have one.

Your 2008 Dodge Magnum key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.
Find CR2032 batteries on AmazonHow to replace the battery
- 1 Slide the release latch and pull the metal emergency key out of the fob.
- 2 Use that key (or a coin) to pry the two halves apart at the seam.
- 3 Lift out the old coin cell — note which side faces up.
- 4 Drop in the new battery the same way (printed + side usually faces the back cover).
- 5 Press the case back together until it clicks, then test lock/unlock and push-to-start.
Battery tips
- Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
- Even with a dead fob battery you can usually still start the car by holding the fob against the start button — check your owner's manual.
- If the fob still won't work after a new battery, it may need re-syncing or programming.
