Factory keyless remote does not work on your 1996 Honda Civic Ex The radio volume control knob is also malfunctioning this might be the issue because related to radio?

The malfunction of your 1996 Honda Civic's keyless remote and radio volume control knob may be related, as both are connected to the vehicle's electrical system. Here are a few possible causes and solutions:

1. Battery Issue:

- Check the battery in your keyless remote. If the battery is weak, it may not transmit signals effectively to unlock the doors or control the radio. Replace it with a new battery.

2. Remote Pairing Issue:

- Sometimes, the keyless remote may become unpaired from the vehicle. To re-pair the remote, refer to your Civic's owner manual or consult with a qualified technician.

3. Faulty Radio/Control Unit:

- There may be a problem with the radio unit itself or its control circuit. If the radio volume knob is malfunctioning, it could indicate a faulty connection or a problem with the knob's potentiometer (volume control component).

4. Wiring/Fuse Issues:

- Check the wiring connections to both the keyless remote receiver and the radio unit. Look for any loose wires, corrosion, or damage.

5. Door Lock Switch/Actuator:

- If the remote is unlocking the doors but the radio volume control is not working, it's possible that the door lock switch or the actuator might have an issue.

Since the root cause can be complex, it's recommended to take your vehicle to a trusted mechanic or an authorized Honda service center for a proper diagnosis. They can inspect the electrical systems, check for any malfunctioning components, and provide the appropriate repairs.
