Hello, you may run into more problems than you want, for one thing the codes for any components that have failed or have circuit issues are going to eventually come back after a number of key starts. Second the key fob on this model uses a rolling code method, also to program a key fob again or a new fob you have to have the mechanical key for the vehicle. So, your best bet is to diagnose the issues it is having, if things go wrong, you could be stuck with a car that won't start ever again. If you're getting codes, you can post the codes here and we can look up the criteria for setting those codes and give some direction. But with a missing mechanical key I wouldn't discharge the ECM's memory.
