Sounds like a stuck key on the keyboard. There could be a few possible causes here.

If you have a USB or Bluetooth keyboard you could try using it. In this rest setup you're going to pop the bottom cover and carefully disconnect the keyboard ribbon cable then using the power pads startup the system with the external keyboard plugged in or linked via Bluetooth.

The next step is to see if the battery is blistering causing it to push up on the keyboard. Carefully loosen the battery screws, reconnect the keyboard is this now working better?
The last possibly here is did you spill something into the keyboard? You may end up needing to pull the upper case off and the keyboard - Big job!
