The keyless ignition system does not only give your car a touch of innovative technology but also saves time spent in rummaging your car keys every time you have to go for a drive. It comes with a fob that you can keep with yourself (within proximity). The fob has low-frequency signals which act as an authentication for the keyless ignition system to work. This system has become widely available in vehicles that too at affordable prices. Push-button start ignitions are quite useful for people with health problems like arthritis or Parkinson’s who find it hard to grip on the keys.

You can convert your car to the push-button start and add a keyless ignition by replacing the hot wires with a switch. The hot-wiring process involves two wire ends touching each other to produce ignition whereas a push-button start will use a switch instead. If your key does not work or you have lost it, you will be needing an in-depth- diagram for this purpose. This will provide you better know-how of the positioning of wires. Attach the switch where the wires connect. However, this system is not quite secure as anyone can flip the switch and get in the vehicle.

The push-button start will change your life by bringing the ease of keyless ignition but at the same time, there will be some disadvantages that will make you reconsider your choices. Push-button start does not have a key instead it works with a fob.

A lost fob means you cannot get in

The biggest problem with a push-button start is the fob misplacement. In case you lose the fob you will not be able to open or start the car. You will need professional assistance to unlock and start your car and the whole keyless ignition system would have to be changed.

Lack of Proper Training

Not knowing what you are doing can ruin anything either it’s a gadget or a vehicle itself. Working with a fob and push-button start requires proper training of how to start and shut down the vehicle. if you are not aware of the mechanism and its working, you would end up ruining it.

Battery Problems

Wireless systems are based on batteries which creates a problem of running out of batteries. In case of a fob running put of batteries the system entirely shuts off and you can’t get in the vehicle or be able to start.

    Just curious if I can do the opposite with a push to start. Is it possible to have the push to start removed and to have a traditional turn key ignition in. I absolutely despise push to start. The other question would be if not can I make it so the vehicle needs to “key” to be inserted somehow in order to start the car and if it’s remove the car turns off.

    • Hi David,

      Yes, it is possible, you can do the opposite, but make sure ECM communicates to confirm a “key” code matches. If it is not matched, ECM does not allow the car to start. So keep in mind you need to entirely reprogrammer the ECM to remove the code functionality and switch to regular key ignition

      And For Second Question, I think it is not possible every kit comes with different types of Fobs for these kinds of modification you need to modify the Push button starter kit.

    I have a 05 Honda pilot. The keys won’t work at all so I can’t test which wires are getting power. Can I still install push button start?

    Hello I have a 2009 Audi A6 that has a turn key ignition. Yesterday I removed the key and exited the vehicle, while doing so i realized the chime was sounding and the radio was still on as if I had left the key in the ignition. I got back in, reinserted the key and an indicator on my dash infofmed me that there was an ignition switch malfunction and directed me to take the car to the dealership. Aware of the high cost of parts and labor at an Audi dealership I began looking on Ebay for used Ignitions for my car. While doing so I observed some used push start ignitions for sale as well. I was surprised to see that the turn key and the push start ignitions cost the same. My question is since I’m replacing it anyway could I just buy the push start and have it installed instead? Then I could squeeze a positive out of this negative situation and turn a costly repair into a spontaneous forced upgrade..

    • Hello George, yes you are right if replacement is the only option, then I suggest you go with push-start ignition. it is a DIY task, you just need to read the article and in case of any help just contact us, and save your bucks for Christmas. Happy Saving…

    Hi. I have a 2017 Hyundai Elantra. I have been looking to install a push-to-start button for a while now. Will I see any problems if I go and proceed with switching to a push-to-start?

  • Ben Pirotte

    Hi – super helpful, thanks for the article.

    I ended up snapping a key inside my ignition. I just had a locksmith come out to try and remove the key fragment, since I actually do have spare keys, but we couldn’t get the fragment out. Do you think I could just remove the ignition and install a push to start ignition in my vehicle instead? I can’t actually turn it due to the broken off part lodged inside, so would that create issues? I have a 2005 Mercedes Sprinter.


    • Hi ben, yes sure you can install it without any hassle. All you need to do just remove the key ignition and use its wire to install a push-button start. For more information and wiring diagram about installation see the article.
