My 2000 Mercury cougar anti-theft system won't allow me to start engine. There is a anti-theft light on. With or without remote keyless entry. Mikey does come with a transmitter
Disconnect the battery cables and wait 5 minutes then reconnect them if your alarm sounds use your key fob to stop it then you should be okay also the key you have maybe has a battery in it and it's dead if it was an aftermarket key programmed at Lowe's or home depot look at the key if you see little tabs on the bottom there's a battery in there
