If your Audi A5’s battery is dead and the trunk won’t open, here’s what you can try:
Method 1: Use the Manual Key
- Look near the trunk handle or Audi badge — some A5s have a hidden key slot.
- If your key fob has a physical key inside (usually slides out), insert it into the trunk lock and turn to open manually.
- Some models hide the key slot under the Audi badge that flips up.
Method 2: Use the Rear Seat Pass-Through (if available)
- Fold down the rear seats or use the ski pass-through if your model has one.
- Reach inside with a flashlight and try to manually pull the emergency trunk release (a small lever or cable inside the trunk latch area).
Method 3: Jump the Car via Engine Bay Terminals
If the trunk can’t be opened and you can’t reach the emergency release, your best bet is to jump-start the battery:
- Open the hood — it should still open manually.
- Look for the jump-start terminals under the hood (positive terminal usually has a red cover).
- Connect jumper cables from another car or a jump pack and give it a few minutes.
- Once it powers up, try opening the trunk normally with the key fob or trunk button.
If you need detailed step-by-step visuals, the service manual for the A5 would show exact locations of jump terminals and emergency releases depending on the model year.
