kresi has a little shameless behaviour in the past

When I bought my used 2003 Taurus I got only one key.
I went to the locksmith to get two more. He said there is a chip inside the key and he has to program it. One key would be 60$ and two would be 85.
OK, I got two for 85$.
I tried all three keys and they worked.
A month later I couldnt start the car with one of the copied keys. The theft light would start to blink.
I disconnected the battery and connected it again and the car would start.
The following days this happened a couple of times. So I thought maybe its the copied key.
I started to use only the original key. And I had no problems for more than 6 months.
Three days ago I used one of the copied keys. everything was OK.
Yesterday my wife drove the Taurus to a store using the original key. After shopping she tried to start the car, but couldnt. I got there, disconnected the battery and connected it again and the car would start.
I drove it, parked and started a couple of times. everything was OK.
But later that day I couldnt start it again.
So looks like the copied keys mess up the whole car.
I dont know if its a coincidence, but the first time the problem occured was a day after I disconnected the battery (to turn the check engine light off).
I havent asked the locksmith yet, if he knows what the problem could be.
Does anyone had the same problem?

Maybe try reprogramming each of the keys first? He also kinda took advantage of you on the 3rd key, as you can program that yourself.

Code:
1. Insert a previously programmed coded key into the ignition.

2. Turn the ignition from the 3 (OFF) position to the 4 (ON) position. Keep the ignition in the 4(ON) position for at least one second, but no more than 10 seconds.

3. Turn the ignition to the 3 (OFF) position, and remove the coded key
from the ignition.

4. Within ten seconds of removing the previously programmed coded key, insert the other previously programmed coded key into the ignition.

5. Turn the ignition from the 3 (OFF) position to the 4 (ON) position. Keep the ignition in the 4 (ON) position for at least one second but not more than 10 seconds.

6. Turn the ignition to the 3 (OFF) position, and remove the second key from the ignition.

7. Within twenty seconds of removing the previously programmed coded key, insert the unprogrammed key (new/valet key) into the ignition.

8. Turn the ignition from the 3 (OFF) position to the 4 (ON) position. Keep the ignition in the 4 (ON) position for at least one second.

9. Your new unprogrammed key is now programmed.**If the key has been successfully programmed it will start the vehicle’s engine and the theft indicator light will illuminate for three seconds and
then go out. If the key was not successfully programmed, it will not start your vehicle’s engine and the theft indicator light will flash on and off rapidly. If failure repeats, bring your vehicle to your dealer to have the
new key(s) programmed.

To program additional new unprogrammed key(s), repeat this procedure
from step 1 for each additional key.

For step 1, I would use the factory key as well...just in case.

And the positions (1-5) start with accessory and end with start:
