The Cadillac STS
(Seville Touring Sedan) is a mid-sized luxury
manufactured and sold by General Motors
from 2004 to 2011 for the 2005 to 2011 model years. All model years of the Cadillac STS have keyless entry remote fob smart keys that are onboard programmable, which means a person can program the keyless entry remote fob smart key with no special equipment other than the keyless entry remote fob smart key programming instructions. The final STS was assembled on May 4, 2011.
The enlarged third generation rear-wheel drive CTS
sedan introduced in 2013 as a 2014 model, similar in size and price to the STS, effectively succeeded it.
