Rockstar adds missile lock-on jammers to 50 more GTA Online vehicles

Rockstar has widened one of GTA Online’s most useful anti-griefing tools, adding Missile Lock-On Jammer support to 50 more vehicles as The Kortz Center Heist lands in Los Santos. The upgrade costs GTA$400,000 per vehicle, but it gives garage cars a real answer to Oppressor Mk II rockets, homing missiles and aerial attacks that can ruin a free-roam run in seconds.

The timing fits the new heist rollout. The Kortz Center Heist launched July 14 and sends players into the Kortz Center in Pacific Bluffs with Mr. Faber and his fixer Raf De Angelis, either solo or with a crew of up to four. Rockstar says the gallery holds prized artworks and secondary targets that stack up quickly, while mansion owners can add an Art Studio to start prep, host friends and assemble gear and tech for the finale.

The jammer is still an Imani Tech mod, installed through the Agency Vehicle Workshop that arrived with The Contract update on December 15, 2021, alongside Franklin Clinton, Lamar Davis, Chop and Imani. That is the part that matters for day-to-day play: this is not a speed tune or a flex piece, it is survivability. The vehicles that get the upgrade become much better choices for running between properties, moving through mission nodes and crossing public lobbies without turning into easy lock-on bait.

Rockstar had already expanded Missile Lock-On Jammer compatibility to 50 more vehicles in the June 17, 2025 Money Fronts update, which also made several mission-replay cutscenes skippable, doubled all sources of Arena Points and delayed the global signal timer for Sell Missions in public sessions. The Kortz Center change pushes that defensive logic deeper into the current content wave, where new property buys and heist prep are arriving alongside the usual missile-heavy lobby nonsense.

For players tired of getting chased off the map by lock-on spam, the appeal is obvious. The jammer does not delete every threat in free roam, but it does shift the balance toward cars you can actually trust when the lobby turns hostile. In a game that keeps selling faster toys and louder weapons, giving 50 more vehicles a way to shrug off the most annoying attacks is the rare upgrade that feels built for survival first.
