A Guide to the 2012-2019 Hyundai Elantra Ignition Switch
If your Elantra won't start, stalls, or has flickering lights, your ignition switch could be the problem.
- Symptoms like 'no-start' or stalling can point to the ignition switch.
- Be aware of other common Elantra issues, like a faulty inhibitor switch (TSB 19-AT-024H), which has identical symptoms.
- Replacing only the electrical switch is a cost-effective DIY repair; replacing the lock cylinder is more complex.
- Aftermarket brands like Standard Ignition offer high-quality, reliable replacements.
Is Your Elantra's Ignition Switch Failing?
A bad ignition switch can cause problems that seem random at first. Because it controls power to so many systems, the symptoms can be confusing. 🎬 Watch: A quick guide to common ignition switch failure signs. Watch for these common signs in your 2012-2019 Elantra.
Top 5 Failure Symptoms
- Car Won't Start or Crank: You turn the key or press the button, and nothing happens. You might hear a single click, or there might be complete silence from the engine. This is the most common sign of a failed switch.
- Intermittent Starting Issues: Your Elantra starts fine one day but refuses to start the next. This can be caused by worn electrical contacts inside the switch that only work sometimes.
- Stalling While Driving: This is a serious safety issue. A faulty switch can lose connection while you're on the road, cutting power to the engine and causing it to shut off without warning.
- Flickering Lights and Accessories: You may notice the dashboard lights, radio, or climate control cutting in and out. This happens because the switch isn't providing a steady flow of power.
- Key is Hard to Turn: While this is often a problem with the mechanical lock cylinder, a binding or failing electrical switch behind it can also make the key difficult to turn. 🎬 See how to replace a jammed ignition lock cylinder.
Known Issues & Common Misdiagnoses for 2012-2019 Elantra
Inhibitor Switch (TSB 19-AT-024H): Many Elantras in this year range can have an intermittent no-start problem caused by a faulty inhibitor switch (also called a neutral safety switch). The car doesn't recognize it's in Park or Neutral and won't let the engine crank. The symptoms are nearly identical to a bad ignition switch. A mechanic can check for codes like P0705 or P0706 🎬 Watch: How to fix an intermittent neutral safety switch issue. to confirm if the inhibitor switch is the real problem.
Theft-Related Damage: Turn-key ignition models from these years are known targets for theft due to a lack of an engine immobilizer. If your car was broken into, the ignition lock cylinder might be damaged. This is physical damage from the theft attempt, not an electrical failure of the switch itself. Hyundai has a service campaign to install anti-theft software. Push-to-start models have an immobilizer and are not part of this specific theft trend.
Choosing the Right Aftermarket Ignition Switch
When buying a replacement, you'll see different prices. The lower-cost parts are usually just the electrical switch itself. The more expensive options are often a complete assembly that includes the mechanical lock cylinder and new keys. If only your electrical switch has failed, you don't need the full assembly.
- Premium Aftermarket (Standard Ignition): Standard Motor Products (SMP) is a highly respected brand in the auto repair world. Their parts are known for being reliable and are often considered equal to or even better than the original factory parts. Choosing a Standard Ignition switch is a solid bet for quality and long life.
- Standard Aftermarket (Rostra Powertrain): Rostra is another established brand that provides dependable replacement parts. These are a good, cost-effective choice for getting your Elantra back on the road and restoring original function.

DIY Pro Tip
Replacing just the electrical ignition switch is often a straightforward job. It usually involves removing the plastic covers around the steering column, unplugging the old switch, and plugging in the new one. This can save you over $100 in labor. However, if you are replacing the entire lock cylinder assembly, it may require special tools and key reprogramming.
Frequently Asked Questions
Is my ignition problem related to the Hyundai theft issue?
It depends. If your car was broken into and the key slot is physically damaged, then yes. However, if your car is experiencing electrical symptoms like stalling or intermittent starting without any physical damage, it is more likely a standard part failure. A free anti-theft software update is available from Hyundai for turn-key models to help prevent theft.
Do I need to reprogram my keys after replacing the switch?
If you only replace the electrical ignition switch, you do not need to reprogram your keys. If you replace the entire ignition lock cylinder assembly, which comes with new keys, then reprogramming will be necessary for the car to recognize them.
What's the difference between an ignition switch and a lock cylinder?
The ignition lock cylinder is the mechanical part you put your key into. The ignition switch is the electronic part behind it that actually sends power to the car's systems. They are two separate parts but work together. On push-to-start models, the button and the switch are integrated differently but serve the same function.
My car won't start, but the battery and starter are good. Is it the ignition switch?
It could be, but for the 2012-2019 Elantra, you should also suspect the inhibitor switch (neutral safety switch). A faulty inhibitor switch will prevent the car from starting even if the battery, starter, and ignition switch are all working perfectly. It's a very common issue on these models.
