Chrysler 300 Key Replacement
From $120 | Locksmith Auto

The Chrysler 300 is one of the last big American sedans still on the road, and Florida has plenty of them. 2005-2010 first-generation 300s use the Chrysler Sentry Key immobilizer with a standard transponder key and separate fob. 2011-2014 models transitioned to an integrated key fob on higher trims. From 2015 onward the 300 comes standard with a proximity smart key and push-to-start on every trim level. The Stellantis platform encryption has gotten tighter with each model year.

A transponder key for a 2005-2014 Chrysler 300 starts from $120 at Locksmith Auto. Integrated remote keys run from $150. Proximity smart keys for 2011+ models start from $200. Chrysler dealers charge $300-450 for a 300 smart key, plus a separate programming fee of $80-150. The base transponder key still costs $250-300 at the dealer. With Locksmith Auto you save $100-250 on every Chrysler 300 key.

The Chrysler dealer route for a 300 key means a tow truck if the car will not start ($100-200), a 3-5 day wait for a service appointment, and a final bill that can top $500 for a proximity key.
