If you need brakes attendibg to, you might as well do the clutch and get all the issues sorted by bringing forward the date for the brake shoes.
I see little point in waiting around.
On the key fob issue, I change my key fob batteries on all three cars every three years without waiting for them to fail even though the fob works fine. It is a small cost versus the inconvenience and embarrassment of being locked out and frustrating people with the alarm going off.
The Porsche key requires reprogramming if it fails - expensive. It needs PIWIS dealer level diagnostic reader, also available at some indys. Price at indy for reprogramming is similar to main dealer price for modern classic porsche cars.
When I bought the Gransport, at the first service, I got Autoshield to change both key fob batteries and again 3 years later.
