If your Jeep key fob is cracked, worn out, or just looks tired, this replacement shell is exactly what you need. It's a brand new red case designed specifically for the M3N5WY783X / IYZ-C01C remote used in Jeep Grand Cherokee (2008-2013) and Commander (2008-2010) models. Important: This is just the empty shell—it doesn't include any electronics, chips, or batteries. You'll carefully transfer the internal circuit board and key blade from your old remote into this new case. No programming is required, just a bit of careful swapping. It's a great way to make your remote look new again without paying dealership prices. The case feels solid and fits perfectly. Before you buy, double-check that your existing remote has the same model number and doesn't have a battery door on the back (this case won't fit if it does). An easy, cost-effective fix to refresh your key fob!
