Symptoms
- No button does anything on any device
- Remote used to work fine, now completely dead
- Buttons feel normal (not stuck) but nothing happens
- LED indicator on remote (if any) doesn't light when pressed
Likely causes
- CommonDead batteriesThe most common single cause of a totally unresponsive remote.
- CommonBatteries inserted with wrong polarityReversed batteries prevent the remote from powering on at all.
- PossibleCorroded battery contactsOld leaked batteries can leave residue that blocks the electrical connection.
- Less commonFailed IR LED emitterThe emitter itself burns out, more likely after the remote was dropped or exposed to liquid.
What to do
- Replace the batteries with fresh ones, checking the polarity markings inside the battery compartment.
- Remove the batteries and inspect the contacts for white/green corrosion; clean gently with a cotton swab and a bit of vinegar or contact cleaner if found.
- Use a phone's camera (most phone cameras can see infrared light) to look at the remote's front emitter while pressing buttons; a flashing light means the remote is transmitting.
- If no flash appears on camera even with new batteries, the remote's emitter or internal circuit has likely failed.
- If the light does flash but no device responds, the issue is likely with the device's receiver, not the remote.
- Try the remote on a completely different device to confirm whether it's the remote or the original device at fault.

When to call a pro
Not typically needed; a confirmed-dead remote is more cost-effective to replace than repair.
