You have a legitimate concern. California Civil Code section 1941.3 imp[oses on the landlord the duty to "install and maintain an operable dead bolt lock on each main swinging entry door. . . "
He is also required to "install and maintain operable window security or locking devices for windows that are designed to be opened."
You must notify the landlord. I suggest you contact the landlord, politely of course. Point out the safety problem and your concern. He should arrange for a locksmith to promptly rekey your door and install dead bolts if they are not there already, and locking devices on any windows that open and do not have them.
If he refuses, tell him that you must do it and deduct the bill from the next rent payment. You have that right under CC Section 1942. Alternatively, you have the right to vacate the premises.
