2010-2013 Suzuki Kizashi Ignition Switch: No-Start Issues and Key Programming Secrets

Symptoms of a Failing Ignition Switch

A problem with the push-button ignition switch can prevent the car from starting, leaving you stranded. While other issues can cause similar symptoms, a faulty switch itself often presents with specific behaviors.

• No Response When Pressed: The most common symptom is a completely dead button. You press it, and nothing happens—no accessory power, no dashboard lights, and no attempt to start.
• Intermittent Starting: The button may work sometimes and fail at others. You might need to press it multiple times before the car responds.
• Accessory Mode Works, But Engine Won't Crank: The radio and dashboard lights may turn on, but pressing the button further does not engage the starter motor.
• Unusual Clicking Sounds: You might hear a single click from the dashboard or a rapid clicking sound when pressing the button, but the engine doesn't turn over. This can point to the switch, a relay, or the starter itself.
• Stuck or Sticky Button: The physical button may feel stiff, get stuck in the depressed position, or lose its normal tactile feedback.

Diagnosing Starting Problems

Follow these steps to determine if the ignition switch is the source of your no-start condition.

1. Check the Key Fob Battery: If the dashboard displays a "Key Fob Not Detected" or "Key Battery Low" message, the first step is to replace the CR2032 battery inside the fob. This is the most common and cheapest fix.
2. Check the Car Battery: Use a multimeter to ensure the main 12V car battery has a healthy charge (at least 12.4V). A weak battery can cause the starter to click or may not provide enough power for the vehicle's computers to operate correctly.
3. Check the Brake Pedal Switch: The Kizashi requires the brake pedal to be depressed to start the engine. If the brake pedal position sensor is faulty, the car will not send power to the starter. Ensure your brake lights are working; if they aren't, this sensor could be the culprit.
4. Scan for Diagnostic Trouble Codes (DTCs): Use an OBD-II scanner to check for codes. The Keyless Start System in the Kizashi can store specific codes related to the switch and immobilizer system. Look for codes such as:
   • B1511 / B1512: Engine Switch Circuit Malfunction
   • B1502: Keyless Start Control Module Internal Malfunction

Known Issues, Recalls, and TSBs

While the 2010-2013 Suzuki Kizashi was subject to several safety recalls, none of them directly address the push-button ignition switch.

It is important to be aware of other major recalls for this vehicle, as their symptoms could be misdiagnosed:

• Fuel Tank Crack (NHTSA 18V-872): Spiders could weave webs in a vent line, causing negative pressure that could crack the fuel tank, leading to a fuel leak and fire risk.
• Occupant Classification System (OCS) Failure (NHTSA 19V-813): The passenger seat sensor could fail to detect an adult, disabling the airbag.
• Shifter Interlock Failure (NHTSA 14V-118): The gear selector could be moved out of Park without depressing the brake, creating a rollaway risk.

No Technical Service Bulletins (TSBs) specifically related to the failure of the ignition switch button have been widely published.

Programming & Immobilizer Information

This is the most critical area of confusion for this part. Understanding how the system works is key to a successful repair.

Does a Replacement Ignition Switch Need Programming?

No. The ignition switch itself (part number 37290-57L00) is a simple electronic button. It is a plug-and-play component and does not contain any programmable data. You can swap a used switch into your vehicle without any special tools or procedures.

When is Programming Required?

Programming is required when you replace the key fobs or the Keyless Start Control Module / Body Control Module (BCM). The keys contain a transponder chip that is electronically registered to the vehicle's immobilizer system.

• Lost or New Keys: A new key fob must be programmed to the vehicle by a Suzuki dealer or a qualified automotive locksmith using a diagnostic tool.
• After Battery Replacement: Sometimes, after disconnecting the main 12V battery, the car may "forget" the keys and the immobilizer will prevent starting. You can often perform a simple reset procedure without a scan tool.

How to Reset the Immobilizer After a Battery Change

If your car cranks but won't start or the security light is flashing after a battery swap, try this relearn procedure before calling a mechanic:

1. Insert the key into the ignition (or have the fob in the car).
2. Turn the ignition to the 'ON' position (do not start the engine).
3. Leave it in the 'ON' position for 10-15 minutes. The security light on the dash may blink and then turn solid or go off.
4. Turn the ignition 'OFF' and wait 10 seconds.
5. Attempt to start the engine normally.

Buying a Used Ignition Switch

A used OEM ignition switch is an excellent, cost-effective option for the Kizashi. Since it's a simple electronic component with a low failure rate, a tested part from a reputable automotive recycler is a smart choice over trying to source a rare and expensive new part.

What to Look For:

• Verify the Part Number: It is essential that the part you buy is 37290-57L00. This switch was used across all 2010-2013 Kizashi models with keyless start.
• Inspect the Connector: Check the electrical connector pins for any signs of corrosion, dirt, or damage. The connection should be clean and bright.
• Test the Button Feel: The button should press in smoothly and return to its original position without sticking. It should have a distinct 'click' feel.
• Purchase with a Warranty: Only buy from sellers who offer a warranty and a return policy. This protects you in case the part is defective.

Cost Comparison

Note: The total cost for a professional replacement using a new OEM part was estimated by RepairPal to be between $418 and $464. Using a recycled OEM part can result in significant savings.
