How do I go about checking a key chip?

20

Asked by Thomas Jan 28, 2023 at 09:44 PM about the 2005 Mercury Grand Marquis GS

Question type: General

The theft light flashes quickly when the key is in the "ON" position. My

understanding is that there is a fault related to the



PATS system.







I have one key; a non original key.







Is there an alternative than to take my vehicle to dealer or locksmith to have it

programmed with a dealer type scanner?
