Mechanic Wiki: How to Program a Hyundai Entourage Key: DIY With 2 Keys (2007-2012)

Learn how to program a Hyundai Entourage key yourself with two working keys. Step-by-step guide for 2007-2012 models, plus troubleshooting tips and costs for dealership or locksmith.

Quick Answer

If you have two working keys, you can program a third Hyundai Entourage key yourself in about 30 seconds using a simple ignition sequence. With only one working key or none, you’ll need a locksmith or dealership to program a new key — the DIY method requires two existing keys. The process involves inserting and turning keys in the ignition in a specific order without starting the engine.

Before You Start: What You’ll Need

Gather these items before you begin programming:

At least two existing working keys – the DIY method won’t work without them.
A new, uncut transponder key that matches your Entourage. For models built between 2007 and 2012, the key contains a built‑in chip and often an integrated remote fob.
Proof of ownership and vehicle registration – locksmiths and dealerships will ask for these.
Optional: A diagnostic programmer like the Autel IM508 or Xtool X100 if you want to bypass the dealer in a one‑key scenario.

Note: The key must be physically cut to fit the ignition before you can program it. A blank key will not turn the lock cylinder.

Understanding Hyundai Entourage Key Types

The Entourage uses two separate but related systems:

Transponder key – a chip inside the key head communicates with the vehicle’s immobilizer. The engine will not start unless the immobilizer recognizes the chip’s unique ID.
Remote fob – controls the door locks, panic alarm, and sometimes the sliding doors. On many Entourage models, the remote is built into the key head.
Integrated key/fob – the most common style on later Entourages. The programming sequence below handles both the immobilizer chip and the remote in one go for most years.

Programming Methods by Situation

Method 1: DIY with Two Working Keys

This procedure works for most Hyundai Entourage models from 2007 to 2012. Follow each step without pausing too long between actions.

Insert the first working key into the ignition and turn it to the ON position. Do not start the engine. The dashboard lights should illuminate.
Wait 1–2 seconds, then turn the key back to OFF and remove it.
Immediately insert the second working key, turn it to ON, wait 1–2 seconds, then turn it OFF and remove it.
Within 10 seconds, insert the new key and turn it to ON.
Leave it in the ON position for about 5 seconds until the security light (usually a car icon with a key) stops blinking or turns off.
Turn the new key OFF and remove it.

Test the key: Start the vehicle. If it cranks and runs, programming succeeded. The remote functions (lock/unlock) should also work automatically.

Method 2: When You Have Only One Working Key (or None)

If you do not have two working keys, the DIY method will not work. Choose one of these options:

Option A: Dealership – Provide your VIN, proof of ownership, and any existing keys. The dealer uses factory equipment to program the immobilizer and erase lost keys. Expect to pay $80 to $150 per key (plus the cost of a blank key).
Option B: Automotive Locksmith – Many mobile locksmiths can program Hyundai transponder keys on‑site. They typically use a universal programmer like the MVP or AutoProPad. Cost: $60 to $120.
Option C: Self‑Programming with a Diagnostic Tool – If you own a high‑end scan tool such as the Autel IM508 or Xtool X100, you can bypass the need for two keys. Follow the tool’s “All Keys Lost” procedure for Hyundai. You will need a security PIN, which you can obtain from the dealer (using your VIN) or through a paid subscription service.

Warning: Attempting to program a key with only one working key using aftermarket tools carries some risk. If you choose the wrong procedure or enter an incorrect PIN, you may lock the immobilizer. Research compatibility carefully or hire a professional.

Troubleshooting Common Programming Problems

New Key Not Starting the Engine

A few things can go wrong. Check these first:

Key not cut correctly – compare the new key side‑by‑side with an original. The cuts must match exactly.
Chip missing or damaged – some aftermarket blanks are non‑chip copies. Make sure your blank contains a transponder chip.
Programming sequence timed out – repeat the steps. Keep each turn brief (1–2 seconds) and the total sequence under 60 seconds.
Wrong model year procedure – the 2006 Entourage (first year) may use a different sequence. Consult your owner’s manual. For 2007–2009, the sequence matches the Hyundai Santa Fe of the same era.

Security Light Stays On (Fast Blinking)

A rapidly flashing security light indicates an immobilizer error. Try these fixes:

Disconnect the battery for 10 minutes to reset the system, then repeat the programming.
Verify that the new key’s chip is compatible (T5 or T6 transponder type).
Use a different working key – one of your existing keys may have a weak chip or a dying battery in the fob.

Remote Fob Doesn’t Lock or Unlock

The DIY sequence above usually programs the remote as well. If the remote functions still do not work, try this dedicated fob programming procedure:

Sit in the driver’s seat with all doors closed.
Insert a working key, turn it to ON, then OFF, and remove it.
Press the LOCK button on the remote fob three times.
Turn the ignition to ON again, then press the LOCK button three times.
Remove the key. The doors should lock and unlock automatically to confirm.

Additional Considerations

Year variations: The procedure above applies to most 2007–2012 Entourage models. The 2006 model year may require a different sequence. Always verify with your owner’s manual or contact a Hyundai service center.

Where to buy replacement keys: Dealerships offer guaranteed fit but charge a premium (keys typically cost $30–$60, plus programming). Online retailers like KeylessEntryRemote or eBay sell pre-cut or uncut blanks at lower prices — just confirm the transponder type before purchasing.

Battery drain: If your remote stops working after programming, replace the coin battery inside the fob. The Entourage uses a CR2032 battery, which you can find at any electronics store.

Duplicate vs. new key: A duplicate (cloned) key copies the transponder ID from an existing key and does not require programming. A true new key has a different ID and must be added to the immobilizer’s memory using one of the methods above.

Frequently Asked Questions

Can I program a Hyundai Entourage key without a working key?

Not with the DIY method. You will need a dealership, locksmith, or an advanced programmer that supports “all keys lost” procedures. Expect to pay more for these services.

How much does it cost to have a dealer program a key?

Typically $80 to $150 per key, plus the cost of the key blank ($30 to $60). Locksmiths are often cheaper, ranging from $60 to $120 total.

Will a copied key work without programming?

A simple metal duplicate will turn the ignition, but the engine will not start because the immobilizer will not recognize it. Only transponder keys with the correct chip need programming.

What if the new key won't turn in the ignition?

The key is not cut correctly. Compare it to your original key side‑by‑side. The cuts must match exactly for the lock cylinder to rotate.

Do I need to program both the key and the remote separately?

No — the standard DIY sequence programs both the transponder chip and the remote fob at the same time. If the key works but the remote does not, use the dedicated fob programming steps listed in the troubleshooting section.

How many keys can I program to a Hyundai Entourage?

Up to 4 or 5 keys, depending on the immobilizer module. When you add a new key, the system remembers all previously programmed keys. You do not need to reprogram existing keys.

What if my security light blinks rapidly after programming?

Try the process again with a fresh battery in the new key. If the light still blinks, the chip may be faulty or incompatible. Contact the seller for a replacement.

Final Tips

Always keep two working keys on hand to avoid expensive locksmith calls.
If you lose all keys, the dealer must program the immobilizer from scratch, which can cost over $200.
For 2010 and later Entourage models, the programming sequence may differ slightly. Check your owner’s manual or call a Hyundai service center before attempting the DIY method.

By following the correct approach for your situation, you will save time and money while getting your Hyundai Entourage back on the road.
