6 Best Auto Key Programmers 2022 [Review & Comparison]

If your car/truck key is lost or the key fob is broken, getting a replacement can be a hassle – and depending on what kind of vehicle you drive, it can cost a pretty penny.

A car key programmer allows you to reprogram keys, program new keys, and adjust the IMMO system to get back on the road, saving you both time and money.

Some automotive scan tools have key programming features built-in. These models are often designed for experienced DIY-ers or professionals. A stand-alone key programmer is a more affordable option for drivers or locksmiths who don’t need a scan tool’s functions. 

I make sure that after reading this guide, you will find a suitable one for your car key.

AUTEK iKEY820

Autel Ikey820
Autek Ikey820 Professional Auto Key Programmer
3.9
Given the versatility, Autek Ikey820 is recommended for locksmiths. However, nothing is stopping you from buying it for personal use.

AUTEK iKEY820 is a professional auto key programming tool with unrivaled IMMO capability. It can read mixed data from almost any car model, making it the best tool for locksmiths, garage, and car body repair centers. AUTEK iKEY820 has an interactive user interface that makes it easy to operate. Even beginners can find it easy to use in performing IMMO functions.

AUTEK iKEY820 is best known for key programming and does not have token limitations. The tool comes preloaded with 500 tokens, but you can always charge up to 200 for free.

This key programmer does not require an additional power source to operate. It is a plug-and-play tool that uses an OBD2 port to perform any required key programming functions, which include the following:

  • Provide Roadside key & Remote Programming for Drivers
  • Read & Clear Fault Codes
  • Clear key Memory
  • Program Proximity & Non-Proximity Keys

A key programmer of this level should have been equipped with the full capability to handle all functions related to IMMO services.

The Autek ikey820 is also relatively heavy. It has a net weight of 1.5 Kg, which makes operation with one hand nearly impossible.

Ck100 universal key programmer

CK-100 Cheap Universal Auto Key Programmer
4
CK100 auto key programmer is the most affordable product on this list. This does not mean it is less effective since it can perform all programming functions as other products here. It is compact and portable, appropriate for both car owners and locksmiths.

CK100 is a cost-effective key programmer for beginners. It has many IMMO functions and covers a wide range of vehicles worldwide. It is made of high-quality ABS material, making it suitable for use under different conditions.

The CK100 key programmer comes with a 1024 token, which can be updated for free once depleted. However, it has none for some cars. That can be viewed as a disadvantage if you handle different vehicle brands and models. It can also fail to adapt keys when in use. In such cases, users are supposed to disconnect the OBD16 adapter and reconnect after 10 seconds.

CK100 has the following features and functions:

  • Program a replacement button.
  • Read the key from the anti-theft lock memory
  • Disable the keys owned by the owner
  • Operate through menu-guided programming
  • Program a replacement remote
  • Complete database software containing all the major vehicle brands

The CK100 is not as durable as it’s supposed to be. It will die after a few months of use. Also, it doesn’t work on all vehicle brands and models. The advertised information on Amazon may be misleading as the CK100 cannot program the 2001 Honda Accord or Acura. Some Toyota models are also not supported.

Key Programmer Buying Guide

What can I do with a key programmer?

Most key programmers will offer various features, from merely programming new keys to replacing all the keys and resetting the vehicle’s security systems. The most common features include:

  • Add a key/ new key programming. This function allows you to create a new key for the car from a blank, without deactivating the existing keys.
  • Reset/relearn keys. If your existing keys have malfunctioned, this function helps reset them back to their original operation. 
  • New remote control programming. Remote controls and key fobs can be programmed to work with your vehicle using this function. 
  • Key cloning. This feature makes a copy of an existing key by cloning its information into a blank. 
  • Read keys from IMMO memory. With this function, you can generate new keys straight from the vehicle memory. It allows you to make replacements even if you’ve lost the originals. 
  • All keys replaced. If you don’t have any of the original keys, this function allows you to generate a whole new set. Doing so will also deactivate the old ones.
  • PIN code reading. The PIN associated with your IMMO system is stored in your vehicle’s computer memory. With this feature, you can retrieve the PIN and use it to make new keys or remotes. 
  • Reset immobilizer. This function helps reset the vehicle’s security system, troubleshoot problems, or get the system to recognize new keys. 
  • Program immobilizer. IMMO programming gives you more in-depth control over the vehicle’s electronic security, allowing you to alter the parameters or even deactivate them.

What to Consider Before Buying a Key Programmer?

Types of Key Programmer

Car key programmers are broadly classified into Universal key programmers (for all cars) and Key programmers with OBD2 diagnostic functions (2in1). What do they offer, and how do they differ?

Universal key programmer (for all cars/trucks)

As the name suggests, a universal key programmer can program keys for all cars. It can allow you to duplicate your car key, reset keys, clone keys, replace keys, program and reset immobilizers, among others. Compared to a car key programmer with OBD2 diagnostic functions, universal key programmers are cheaper.

Key programmer with OBD2 diagnostic functions (2in1)

Apart from the features offered by the universal key programmer, they also provide OBD2 diagnostic functions. These key programmers can read and clear error codes and can also allow you to view freeze frames, live data, and other helpful information from your car engine. Due to these additional capabilities, these auto diagnostic tools are more expensive.

How much should I pay? – $100-$500

Generally, how much you pay for a car key programming tool will be dependent on which features you need to have included. You can break the tools down into three broad price ranges:

$100-$250: These tools will only program new keys from the vehicle’s memory or deactivate old keys you no longer have. They’re a budget-friendly option for both car owners and locksmiths and are typically simple and straightforward in their operation.

VVDI key programmer is equally versatile but is more affordable. If you are limited on the budget but still desire to buy a key maker with such functionalities, this is an appropriate choice.

$250-$500: Auto key programmers in this price range tend to combine the key/key fob programming abilities with an OBD2 scan tool’s full diagnostic functions. Intermediate to advanced home mechanics may find them a good value if you plan to make other repairs. They don’t usually go beyond the functions of less expensive ones when it comes to key/key fob programming abilities, so they don’t offer any more significant value to locksmiths.

Recommendation: Launch CRP429C OBD2 Scan Tool with Key Programming

Types of car key and their replacement cost

Six main types of car key and their replacement cost
There are six main types of car key. Among them, replacing a master key can cost more than the vehicle is worth.

Traditional key

The traditional key is the manual metal key that cars have used since their invention. Since there are no electronic components, they don’t require any coding. A copy can be made by cutting a blank to the correct shape to fit the lock and ignition. The blanks only cost about $3-$10. Some locksmiths will also charge for labor, but even so, it’s the cheapest option to replace

Master key

You won’t see master keys often in modern vehicles. They typically came with older cars that used traditional keys and were not designed to be used. Instead, they exist as a template off of which to make additional copies. 

Replacing a master key can cost hundreds of dollars. If you’re buying an older used car, check the manual to see if it should have a master key. In some cases, the entire engine management system needs to be replaced if the master key has been lost, which can cost more than the vehicle is worth.

Transponder key

In use since the mid-’90s, transponder keys are metal but have a chip in the handle. The transponder is activated when the key is in the ignition, disabling the car’s IMMO processes and allowing it to start. 

Copying a transponder key costs around $40 to $100. If it’s lost, you’ll pay about $150-$250 to replace it, depending on whether you go through a locksmith or a dealership. The most expensive transponder keys are rolling code keys. They’re more secure and more challenging to reproduce and can cost $500 or more to replace. 

Switchblade key

These keys have a traditional metal component that folds into a plastic fob, similar to how a switchblade knife works. Replacements usually cost between $200 and $300, though it’s less if you only need to replace the shank (usually around $75-$100).

Valet key

These keys will unlock the doors and start the car but won’t open the trunk and limit functions in other ways. The style of the car key will determine how much it costs to copy or replace. 

Smart key

The most advanced keys in use, smart keys, let you turn the car on by pushing a button as long as they’re within your vehicle’s range. These keys can be some of the most expensive to replace because you can only get them through your dealership. If it’s lost, expect to pay anywhere from $200 to $400 for a replacement. 

What is car key programming?

The chips in transponder keys and smart keys are programmed to interact with the specific vehicle they’re associated with. The car key programming process is done at the factory when your car is first sent out or at the dealership when you go in to get a key replacement or copy.

Car key programming devices allow you to sync new keys with a vehicle rather than going to a dealership to have it done. Since it uses information taken directly from the vehicle’s computer to create a unique key that will only operate that vehicle, it’s just as secure as having a new one made by a professional.  

How to Use a Car Key Programmer

how to use a car key programmer
These are four steps you should do to use a car key programmer but the first thing you’ll need to do is get a blank key that works with your vehicle

The first thing you’ll need to do is get a blank key that works with your vehicle. You can order these online from your vehicle manufacturer for much less than you’ll pay to have a key made. 

The exact process of using a key programmer varies depending on the tool and what kind of locking system your vehicle uses. Most tools you buy will walk you through the process, either with an on-screen wizard or in the repair manual.

Generally, you start by plugging the programming tool into the diagnostic port, then choosing your vehicle’s make and model from the menu. It will show you the password or pin code for the vehicle’s IMMO system to program this into the new key. Many of these tools can also remotely turn on the ignition, a beneficial feature for programming new smart keys for keyless ignition systems.

FAQs

1. Can I Program A Car Key Myself?

4. What do locksmiths use to program keys?

Automotive locksmiths use an array of specialized equipment to program new keys for vehicles. These include transponder programming and cloning devices and code machines that allow them to read and duplicate pin codes and passwords for vehicle security systems. 

5. How much does it cost to program a key?

That depends on your vehicle and the locksmith you go with. Generally, rekeying a car costs somewhere between $50 and $300. 

6. How long does it take to program a key fob?

Not very long at all. Using an auto key programming tool, you can typically program a key fob in 15-30 minutes. 

7. What scan tool can program keys?
