Issues with PS2 after replacing CMOS battery

Me and my brother recently opened up one of our old PS2s which is an SCPH-30003R. Before we replaced the CMOS battery, the disc drive was shooting out extremely fast, and it couldn't be closed, until we hit the reset button after which it worked and would read games.

Today we replaced the CMOS battery and all is well, it turns on fine and I can set the date and time, but the now the disc drive won't open at all and the blue light has no light at first, but upon pressing it it flashes for about 8-10 seconds before the light goes back off. The console otherwise has no other issues other than this.
