How do you turn off security system

I put a used ctm in with same numbers

You may have to have the PCM reflashed for it to accept the key. The security programming will be different from key to key

There aren't CTM's in Durango's. If you replaced the ECM/TCM, it has to be reprogrammed to your vehicle. If you replaced the BCM, take it back out and buy a new one. Then have it programmed to the vehicle. BCM's are a one time programming.
