POWER DOOR LOCKS, SECURITY SYSTEM - 1999 CAMRY LE
 

Just purchased (as is - no warranty) 99 Camry LE at Toyota dealership ... no security system/ power door key attachment; salesman says key attachment not being made in 99. Can this be true? It just occurred to me that it sounds weird. I thought this security system and the key chain mechanisms available before 99. Can ths be added to car at this point? How expensive would it be? Any ideas?

Thanks,
Lorenzo
