As long as you have left the property vacant and clean, and have returned the key to the landlord, the landlord must return your security deposit within 14 days. If not, your landlord must let you know in writing why he or she isn't returning your security deposit, and how your security deposit is being applied to repair damages that you have caused.   If the landlord fails to give you back your security deposit unjustly, you can sue the landlord in court, and you will likely win a judgment against your landlord for your security deposit.
