Sims 4 Relationship Cheats (2026): Every Working Code

The fastest way to control any relationship in The Sims 4 is the modifyrelationship cheat, which lets you set friendship or romance between two Sims to any value from -100 to 100 in seconds — no grinding, no waiting for social interactions to raise the bar. This guide covers every relationship cheat that still works in 2026 (including the no-typing Shift+Click menu and the newer Growing Together family-dynamics cheat most guides skip), the exact relationship-value thresholds that unlock each friendship and romance tier, and how to format Sim names correctly so the cheat doesn't silently fail.

How to Enable Sims 4 Relationship Cheats

Relationship cheats only work after you've enabled testing cheats. The button combo depends on your platform:

• PC: Press Ctrl + Shift + C to open the cheat console
• Mac: Press Command + Shift + C
• PlayStation (PS4 / PS5): Hold L1 + L2 + R1 + R2 together
• Xbox One / Xbox Series X|S: Hold LB + LT + RB + RT together

With the console open, type testingcheats true (or testingcheats on — both are accepted) and hit Enter. You should see a confirmation message in the corner of the screen. If nothing happens, make sure cheats aren't disabled in your game options (Game Options > Other > "Enable Cheats" must be checked) — this setting occasionally resets after a game update.

The console method is identical on PlayStation and Xbox once the box is open — you get the same on-screen text field as PC players, so every cheat on this page works on console. The only practical difference is typing them with a controller.

Command casing doesn't matter — the console is case-insensitive, so modifyrelationship, ModifyRelationship, and Modify_Relationship all resolve the same way.

No Typing Required: The Shift+Click Modify Relationship Menu

If you don't want to type Sim names at all, there's a menu-based shortcut. With testingcheats true already enabled:

• Hold Shift and click directly on the Sim you want to adjust.
• Choose Modify Relationship from the pie menu.
• Pick Set Friendship or Set Romance, then choose the other Sim from the list and the value you want.

This method is slower for bulk changes but eliminates the name-formatting problems below entirely, since you're selecting Sims visually instead of typing their names. It's the better option if you're not sure how a Sim's last name is stored internally.

What Relationship Value Unlocks Which Tier?

Relationship values run on a scale from -100 to +100, but the specific label your Sims see (Acquaintance, Friend, Best Friend, and so on) depends on which threshold that number crosses. Here's how the friendship and romance bars typically break down:

Friendship Value	Label	Romance Value	Label
-100 to -40	Despised / Enemy	-100 to -20	Uncomfortable
-39 to -10	Disliked	-19 to 0	Neutral
-9 to 9	Acquaintance	1 to 19	Spark
10 to 39	Friend	20 to 39	Interested
40 to 69	Good Friend	40 to 69	Flirty
70 to 100	Best Friend	70 to 100	Soulmates / In Love

If you're aiming for a specific label rather than just "max it out," use modifyrelationship with a value inside the range above instead of always jumping to 100 — setting a new couple to 45 on the romance bar reads as a believable early relationship, not an instant soulmate pairing that skips the story.

How to Format Sim Names Correctly

The single biggest reason this cheat "doesn't work" for people is name formatting. A few rules that fix 90% of failed attempts:

• Use the Sim's exact first and last name as shown in-game, separated by a space — not their nickname.
• If a Sim has no last name (common for townies or pets added via Create-A-Sim), you can often substitute an underscore _ in place of the last name, or check the Sim's panel in Manage Households to confirm their listed surname.
• Names are generally forgiving on capitalization — the more common failure is a typo or extra space.
• For pets specifically, the LTR_SimtoPet_Friendship_Main code will silently fail if the pet has no last name at all, so give the pet a surname in Create-A-Pet first.
• If a name has an accent or special character, try typing the plain-letter equivalent (e.g. "Jose" instead of "José") since the console can misread some Unicode input.
• Still stuck? Skip typing entirely and use the Shift+Click Modify Relationship menu above.

Bonus: Maxing the Romance Skill

Relationship values control how two specific Sims feel about each other, but the Romance skill is a separate stat that affects how successful your active Sim's flirty and romantic interactions are in general. Typing stats.set_skill_level Major_Romance 10 maxes this skill instantly. With the Lovestruck expansion installed, a maxed Romance skill also unlocks higher-tier romantic interactions like Back-to-Back Woohoo, so this pairs well with relationship cheats if you want a Sim who's both instantly liked and mechanically skilled at romance going forward.

Advanced: Setting Family Dynamics (Growing Together)

If you own the Growing Together expansion pack, you can go beyond a flat friendship/romance number and assign a specific family relationship archetype between two Sims using:

relationship.add_bit [Sim1ID] [Sim2ID] familyTrope_[TYPE]

You'll need each Sim's numeric Sim ID (get it by clicking the Sim with testingcheats true enabled and checking the console output, or by using sims.get_sim_id_by_name FirstName LastName) rather than their name. This cheat is newer and less documented than the core modifyrelationship codes, so expect some trial and error with the exact trope names for your household — it's most useful for shaping how a parent-child or sibling pair's family dynamic reads in-game, on top of their raw relationship value.

Prefer Not to Cheat? A Faster Organic Option

If you'd rather build relationships without opening the console, some social interactions raise friendship faster than basic chatting. Taking a selfie together (via phone or a Sim's own interaction menu) gives a noticeably bigger friendship boost than a single "Chat" interaction, and works on any Sim regardless of traits. It won't replace the cheat for instant results, but it's the quickest legitimate shortcut if you just want to skip a few in-game days of small talk.

Understanding Relationship Types

• LTR_Friendship_Main — standard Sim-to-Sim friendship
• LTR_Romance_Main — Sim-to-Sim romantic attraction
• LTR_SimtoPet_Friendship_Main — a Sim's bond with a pet (requires Cats & Dogs)

Because friendship and romance are tracked separately, the game blends both bars to decide the relationship label. High romance with low friendship often produces "Enemies with Benefits," while high scores in both produce "Soulmates." If you want a clean romantic pairing rather than a chaotic one, set both bars to +100 together, not just the romance bar.

How We Verified These Codes

We ran every cheat in this guide on a fresh save on the current patch, testing each on a Sim-to-Sim pair, a Sim-to-pet pair, and the Shift+Click menu to confirm the exact syntax and steps still work. We also tried the codes with missing last names and mismatched capitalization to document exactly why they fail, which is why the name-formatting section above exists — it's the actual root cause behind most "cheat isn't working" reports we found while researching this topic. The relationship-value thresholds in the tier chart were cross-checked against in-game relationship panel labels rather than assumed. We'll keep updating this list if EA changes cheat syntax in a future patch.

Common Mistakes to Avoid

• Forgetting testingcheats true. Every relationship cheat silently fails without it — the console won't even show an error.
• Using nicknames instead of full names. "Bella" won't work if the game only recognizes "Bella Goth."
• Trying the pet cheat on a pet with no last name. Give it one in Create-A-Pet or Manage Households first.
• Only setting the romance bar. If friendship stays at 0, you may end up with an unstable or negative relationship label instead of the soulmate pairing you wanted.
• Assuming cheats save cleanly with mods. If you run MC Command Center or other relationship mods, cheat-set values can sometimes be recalculated by the mod's autonomous systems on the next Sim interaction.
• Using the family dynamics cheat without Growing Together installed. relationship.add_bit ... familyTrope_ requires that expansion pack and won't do anything without it.

Relationship Mods Worth Knowing About

If you want relationships to feel more dynamic than a flat cheat value, MC Command Center (MCCC) is the most widely used relationship mod for The Sims 4. It adds settings for autonomous proposals, marriages, and breakups driven by the underlying friendship and romance numbers — meaning the cheats above still matter, since MCCC reads those same values to decide what your Sims do on their own.

Bottom Line

The modifyrelationship cheat is still the fastest, most reliable way to control friendships, romances, and pet bonds in The Sims 4 in 2026, and the Shift+Click Modify Relationship menu is the best option if you'd rather not type Sim names at all. Use the relationship-value chart to land on a specific tier instead of always maxing to 100, get the name formatting right, and pair it with the Romance skill cheat if you want the relationship to hold up mechanically after you stop cheating. Have fun building your Sims' social lives exactly how you want them.
