2015 Chevrolet Malibu Key Fob Programming Guide

As an ASE-certified electrical technician and automotive locksmith, I frequently get questions about modern flip keys and key fobs. The 2015 Chevrolet Malibu uses a high-security "switchblade" or flip key that integrates both the remote buttons and the immobilizer transponder into a single unit. While the high-security blade makes it a bit tougher to cut, General Motors generously left an on-board programming procedure in place for owners who already have at least one working key.

Here is your comprehensive guide to replacing, programming, and maintaining the key fob for a 2015 Chevrolet Malibu.

Quick reference

Step-by-step on-board programming

To program a new flip key yourself, you must have at least one currently working, programmed key. Furthermore, the new key's blade must be physically cut to match your ignition before you can perform this procedure. You cannot turn the ignition cylinder to program the transponder if the blade is blank!

Once your new key is cut, follow these steps:

1. Insert the original, working key into the ignition cylinder.
2. Turn the ignition to the ON position. This is the position just before cranking the engine. Do not start the engine.
3. Watch the dashboard cluster. Wait for the anti-theft security light (usually a car with a padlock icon) to turn off.
4. Turn the ignition to the OFF position and immediately remove the working key.
5. Insert the NEW, cut key into the ignition within 10 seconds of removing the original key.
6. Turn the ignition to the ON position. Again, do not crank the engine.
7. Wait for the security light to turn off. Once the light goes out, the vehicle has successfully learned the new transponder and remote frequency.
8. Turn the ignition OFF and remove the key. Test the remote functions (lock/unlock) and then try starting the engine with the new key.

Note: If you have lost all your keys, this DIY method will not work. You will need a professional to program the vehicle.

Battery replacement

When your remote range drops or the dashboard displays a "Replace Battery in Remote Key" message, it's time for a fresh CR2032.

1. Flip the metal key blade out by pressing the chrome release button.
2. Look inside the channel where the key blade normally rests. You will see a small notch or seam splitting the back cover from the main body.
3. Insert a flathead screwdriver or plastic trim pry tool into the notch and gently twist to unclip the back cover.
4. Remove the old battery from the circular housing.
5. Insert the new CR2032 battery with the positive (+) side facing up toward you.
6. Snap the back plastic cover firmly back into place.

Where to buy a replacement fob

When securing a replacement key for your 2015 Malibu, you have a few avenues.

• The Dealership: Going to a Chevy dealer is the safest but most expensive route. They will order the OEM fob (PN 13504200 or 13504259) cut to your vehicle's VIN. Expect to pay between $150 and $250 for the part, plus potential programming fees if you don't do it yourself.
• Local Locksmiths: An automotive locksmith is usually more cost-effective. They stock reliable aftermarket or refurbished OEM fobs and can laser-cut the HU100 blade right in their van. A fully cut and programmed key typically runs $100 to $180.
• Amazon / Online Retailers: You can buy uncut aftermarket fobs for $20 to $50 online. Pros: Very cheap up front. Cons: You still have to pay a locksmith to laser-cut the high-security blade (usually $30-$50). Also, ultra-cheap electronics can sometimes fail to program, leaving you on the hook for the cutting fee with a useless key.

If on-board programming isn't supported

If you have lost all your keys, the DIY on-board programming procedure is completely locked out. The 2015 Malibu uses a robust GM Passkey III+ immobilizer system. Without an authorized key to authenticate the process, the vehicle's computer will refuse to learn a new key to prevent theft.

In an "all keys lost" scenario, you must hire a professional with an advanced bi-directional scan tool or key programmer (like an Autel IM608 or a GM Techline PC). The technician will connect to your OBD-II port, bypass the security gateway, erase the missing keys from the immobilizer memory, and pair the new transponders. Expect this service to cost between $200 and $350 depending on your location and whether a mobile locksmith needs to travel to your stranded vehicle.
