very possible this one has an internal battery that need to be replaced. I am not talking about your radio battery itself, inside there is a coin size battery like a 2025, 2020, 2032, etc. you can get them at radio shack, walmart, lots of places. take the back off and look inside to see. mine did and replaced it and now it works fine. your model may be different, but it is worth a try. if that is not the answer then the memeory chip is bad or the the capacitor on it has failed

clicking noise could be blower motor bearing failure or blower motor fan work itself loose.you can fix.removing lower instrument cover to get to blower motor.you need turn off radio first to keep from losing code then turn off ignition remove keys.you need to disarm airbags by disconnecting the negative battery cable wait 20 minutes before working under dash when done reconnect negative battery cable.when disconnecting negative battery probably have reprogram door locks.and the ECM has relearn memory. some times you have to reprogram radio also you can fix problem but many things has to be reprogram.if first time doing mechanic work best find good mechanic or let dealership fix.

I have exactly the same problem since yesterday. The battery change I did...
But what is reprogramming the remote?

Try manually disarming the system when you hook up the battery cable. After you hook up the cable ( the siren will be going), turn ignition on, press and release valet switch one time. The siren will stop and you will be able to start the vehicle. Test the remote. If the remote is not working, and the battery is good, try reprogramming the remote. Turn ignition on, press and release valet switch one time. Press and HOLD valet switch, press lock button on remote. You will hear a confirmation chirp when the remote is programmed. Turn ignition off. Test system.

1) Manual shows troubleshooting steps. Since ST01C is battery operated, it will not work on loads farther than 100 feet away. If a wire is buried underground, this can interfere with operation. Other electrical devices can interfere with operation. Check for interference issues.

2) Try reprogramming timer
To program the ST01C:

3) ST01C has 1 year warranty + troubleshooting steps in manual, implying short life expectancy. Similar EJ500 has troubleshooting + 1 year warranty. Similar Intermatic EI600 battery-powered has troubleshooting + 5 year warranty. Each offers 40 programs per week.

3) Other in-wall programmable timers offer 7 on and 7 off events per week. Clock operates on 120V instead of battery. Ttroubleshooting is: reprogram.

It sounds like the wall button has the lock feature engauged.

Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.

Good luck.

my remote went blank suddenly. I replaced the batteries and nothing happened. what can I try?

Try changing the batteries. Most times the "tivo" buttons will work but the "tv" buttons will stop working when the batteries are low.

If you have done that, go back into settings and program the remote again for your tv, then give it a shot.
