Subaru Problems? Ask a Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you with your question.
You need to take this to the dealer, the scan tool is needed to reprogram the key fobs. I have also seen the tpms module cause the keyless not to work. You need a scanner to check the keyless and tpms module for codes. If the tpms light is also on this could be the problem. The tire pressure and keyless are on the same module.
Please reply to this if you need more help and we can continue this conversation at no extra charge. This does not have to be my only answer. If you are satisfied with my service, please rate at the top of the screen. Rating does not close out your question. Remember, sometimes it is difficult to completely diagnose your vehicle without being there, but I will try to give you the best answer I can. Hoping to be giving you 5 star service.
Yes the alarm will disable when you start the engine.
