lost keys, cant afford new immobilzer need to bypass somehow

Dear timothy-- Yes, you do have a problem. I remember losing all the keys to a Saab one time and the service department charged us (sales department) $1,000 to replace the immobilizer system. The $500 quote you got from your Acura dealer, therefore, seems like a bargain. Perhaps you could save a bit if you could find a used one. You can find several used Acura parts sources doing a simple search on the Google search engine. And, once you have the new system installed, get an extra key and hide it somewhere to avoid this problem again. Good luck from Bovan.
