Your problem is not very uncommon in CD players.Your player is not dead, just the lens mechanism. It may be a simple error such as "out of alignment" or it may need replacement. Please be aware that the lens mechanism is the most expensive part in a CD/DVD player+ Service you can get a new player for that price. You may want to get a quote so that you can decide whether you want to get it fixed or buy another.

SOURCE: DVD drawer will not open - stuck dvd inside

My only suggestion is to press and hold the eject button for a period of time (15 - 30 seconds). This might unlock the drawer. If not, I would contact Bose Customer Service directly.
