Cheats in GTA IV

In Grand Theft Auto IV, cheats are activated by typing the cheat phone number into Niko's mobile phone. After this has been done once, the cheat will be stored in the phone, and accessible from the "Cheats" menu there.

Be warned that entering some of these cheats in the game will disable certain achievements/trophies, so do so at your own risk. Accessing secrets is different from cheats, and will not affect the status of gameplay. There is no way to unblock the achievements except for re-loading the game without saving after the cheat has been activated. However if a player uses any of these cheats but still desires all the achievements, they can simply start a new game file and complete the first mission. Then there are no blocks on the achievements. Because of the way that cheats work, they may have undesired effects on gameplay, such as glitches.

This article contains information on Cheats.

Using cheats may cause unintended side effects, disable achievements and/or hinder game progress. Use cheats at your own risk.

• Calling any other random number found in the game from stores, posters, etc. will allow Niko or Johnny to prank call that number.
• Note that out-running cops who try to stop the player skipping islands when Niko is in a spawned Jetmax will NOT give the Walk Free achievement, but you can get it later on in the same save file after being killed.
• If the player has completed all 30 of Stevie's Car theft missions, they can spawn any car they want for money like was done in his missions. If the player spawns cars, they can make as much money as they want. The cars are worth about 1/3rd of what they were in his missions but it can be done over and over and over again.

Keep in mind that this table is presuming that the car is just spawned and has not taken any damage.

Vehicle	Price
Cognoscenti	$8,000
Comet	$5,000
Super GT	$11,000
NRG 900	$1,500
Sanchez	$700
Turismo	$10,500

The FIB Buffalo is the only unsellable spawn car. The Annihilator cannot fit in Stevie's garage and it is unlikely the Jetmax will either but it has not been proven.

Most cars have a low sell value, driving gently into a wall enough to scrape the paint will dramatically improve the value of certain cars, when the Super GT is spawned and sold, Niko will get $8,000, driving it slightly into the corner of the garage enough to ding it and then selling it will sell for the full retail value the $10,500. Some have reported the value further increasing to $10,800.
