Not all 1st generation Toyota Tacomas (1995-2004) have keyless entry. For model years 2001-2004, a factory alarm or keyless entry may be equipped with the vehicle. In these cases, a keyless entry remote should be included with the vehicle. If you purchase a new OEM remote and have a dealership program it for you, they might charge you over $100 to do so. Alternatively, you can purchase an OEM remote or a more affordable aftermarket remote, and program it yourself.
