Ok, so this may be a odd question, but is it possible to change the key fobs on the current model Impala Premier? I'm asking this because my GF got a 2016 Malibu LT and I think the keyfob that comes with hers. looks super dope and sleek. So, my question is, can you program the smart key on the Malibu to the Impala Premier? I don't like that pocket knife key fob that's on the Impala Premier. Thanks in advance.

Assuming they are both 2016 models, the part number on the Malibu keyless entry control module is #13506772 (guessing its a 1.5l), the part number on the Impala keyless entry control module is #13580553 . Looking at the wiring schematics for the different modules it doesn't look doable, the male ends from the loom harnesses to the modules aren't matching. To get the malibu's transmitter you would need its corresponding control module and harnesses to start with and possibly the antenna, receiver(#13577251 impala/#13595511 malibu),etc. Looking at my pricing I would estimate about $1000 in parts and at a large number of hundred dollars in labor assuming everything goes to plan lol. I think there are too many systems that piggyback the keyless entry feature to successfully swap a completely different module as disappointing as it is...one of my concerns would be the immobilizer playing nice with its new software/hardware, not to mention the other 15+systems that piggy back the keyless entry. just my two cents. it may be possible but i think path to completion would be expensive, long and hang-over inducing.

Yes, the Malibu has Key-less Ignition. My Mother has a 2017 Malibu with this fob, and the two things I like about it over the Impala Fob is that you have to double push the Trunk Release Button to open it, thus no accidental trunk opening if the button gets pressed while the fob is in your pocket, and it does not have the switch blade key which seems to open when the fob is in your pocket. I wish the Impala and Malibu Fobs were interchangeable.

Accidental trunk opening

the two things I like about it (Malibu fob) over the Impala Fob is that you have to double push the Trunk Release Button to open it, thus no accidental trunk opening if the button gets pressed while the fob is in your pocket, and it does not have the switch blade key which seems to open when the fob is in your pocket.
This is highly annoying too! I work inside an aircraft hanger and three times in a one month period I came outside on break or getting ready to go home to find my (Impala) trunk wide open.

Because of this I currently place my keys inside my tool box while at work but twice I walked out to the car before I realized I needed my keys. I am considering some sort of case to wear on my belt so I can carry the key fob but have it protected from accidental activation.

Would be cool if you could program the fob to require to button pushes to open the doors or trunk.

Resurrecting this thread. I finally got fed up with finding my trunk open at random times. I ordered a 2018+ Equinox key. Same shape as the Malibu key but is it 315mhz. Successfully programmed to the Impala. However the trunk button doesn't work. I assume due to it being a double click instead of single click or because it's for an SUV and Chevy is using a different canbus signal. Might be worth finding a car model key that is also 315mhz and programming. All other functions work correctly.

Our 2014 had this problem when we purchased it used in 2015. I found the below TSB on-line. It outlines reprograming the length of time the remote trunk release button must be pressed to lessen the chance of unintended activation. Dealer performed the update for free, but it was still covered by the CPO warranty at the time.

Wasn't aware of the service bulletin. However like others stated all my buttons are also falling out (unfortunately not the trunk button). For the sake of a thinner more durable key fob, I can give up having remote trunk release, which honestly was only ever used accidentally 99% of the time.
