Adding Remote Start Keyfob to base car?

[CTX148]

Does anyone know if its possible to purchase a used remote start keyfob and then program it to your base 100A/300A or 101A/301A Mustang?

I have FORSCAN so I can enable the remote start feature, but I've read on the 6g forum there might be an issue with frequency if your car didn't come with remote start on the fob itself?

I would prefer if possible to use the fob instead of the app, and was curious if anyone has done this? Plan was to purchase a used 5 button fob and then try to program it to my car.

Following. I too would also be interested to see if there's a way to get remote start working on a 401A with a 6MT via Forscan and coding a Key fob off of an automatic that has the remote start button.

Yes, this is doable. I purchased a new 5-button keyfob (https://a.co/d/jeQme2m for the US, just make sure you're ordering one in the correct frequency for your region) and programmed it myself, then swapped out the backplate with the mustang logo from one of my original keys and transferred over one of my original slide out key. Took a couple attempts to get the programming to stick, but it did finally go through. Programming slot is in the center console underneath the mat.

FWIW I was starting with a non-premium Ecoboost 101A with Active Exhaust. Remote rev already worked from the keyfob from factory, but remote start I could only do from the FordPass app. Now both remote start and remote rev work from the fob.

Thanks! I also have a non-premium Ecoboost 101A w/ active exhaust so hopefully that works as well. I did end up purchasing a used 5 button Mustang key online. I'll have to check and see if the FCC ID lines up when it arrives. If it doesnt, I appreciate the link and will check those out. Fingers crossed it works with a 2020 key as well!
