There is at least one diagnostic fault code memorized in the ABS computer that will lead the mechanic to the circuit or system with the problem, not the specific part. Doing anything to the computer could erase the code and that valuable diagnostic information will be lost.

Once the problem is repaired, the mechanic will use their hand-held computer to erase the codes. That will turn the lights off.

As you changed out the ignition and now have a new key you need to program the new keys into the SKIM computer. For that you need a dealer level scan tool that can program keys or the usually easier process is to have a automotive locksmith come out and program the new keys into the system, If you only have one key you will need a second one as the system needs a minimum of 2 keys programmed in to operate. There is no DIY method of programming in the new keys as you need 2 valid keys in the system to be able to add any keys and with a different cylinder you have no valid keys at the moment.

You can try to erase it with the scan tool, there is an engine code erase feature. Also a check engine light can mean many things and sometimes a sensor could just be going bad and wont store in the computer, but I dont believe that is the case. Try to erase it and keep me posted, or if you dont know how go to autozone, to have it erased, or you can go to your local parts place to do that. You could have a vacuum leak that will cause an engine light and not set a code
