it has a great, organised online checklist to get this ridiculous achievement--you can get all the info there instead of spending $20 on a guide. And you can track it all online with a password account--no printouts necessary.

CAUTION: i didnt realize til 1/2 way thru exactly what was required for this, and burned a bunch of hours because I missed a stranger early on.

ONE OPTION: first playthru strictly for fun, because its a great story. dont bother trying to get the collector achieves, because you'll have to do them again in the "Key" runthru.
Be smart and do Key to the City and the Liberty City Minute in the second (or first) run-thru in 20 or less hours.
I found the jumps very hard to find and to execute even with maps and walkthroughs, so be sure to save before making each jump attempt--sometimes you have to find a specific bike or car on each attempt, and that can really suck up the clock.

this achievement is really not that hard, as long as you have patience, a little bid of combat skill and as long as you remember everything you've done
so first of all you want to do the following:

*beat all story missions (94) these ones require some skill, but arent impossible. you know you are done with this as soon as you get the "You won!" achievement


*once you are done with this you want to complete all 10 of Little Jacob's courier package jobs. you can start these after the mission Shadow, early in the game. you are done with this as soon as you get the "Courier service" achievement


*then you want to start to check your emails from brucie, which you can do after the mission Logging on. he will send you some emails about 10 vehicles he wants to be stolen. if you send him a possitive reaction you will begin the mission. you are done with this as soon as you unlock the "Order Fullfilled" achievement


*now you should start to check your text messages from Stevie. he'll send you the locations of 30 vehicles he wants to be stolen. check out youtube for the locations. when you steel one of the vehicles the game will tell you and you want to go to your garage in Bohan and park your vehicle in here. you dont have to worry about this once you have the "You Got the Message" achievement


*now we want to look for some police cars. steel one and access the computer. you should go to current crimes and choose one. now you start a mission in which you must kill some criminals. complete 20 crimes and youre done with this and you obtain the "Cleaned the Mean Streets" achievement


*now we keep our police car and we're going to look for the most wanted. there will be 10 criminals you want to visite and to shut up. once you are done with the first 10, you should go to the other islands (alderny (west), algonquin (middle) and Bohan/Dukes/Broker (East)) and complete the remaining 20 most wanted missions and you should get the "Manhunt" achievement


*now we should go to alderny (the left island) and, after you have completed the mission Truck Hustle, there should be an Assassination mission on your map. you will need to complete all 9 missions and you will obtain the "Assassin's Creed" achievement


*now you should call brucie to do some races. you need to complete at least 9 of them. but you may want to do 11 more so you get the "Genetically Superior" achievement (THIS IS NOT NEEDED FOR THE KEY TO THE CITY ACHIEVEMENT, but if youre going for achievements, why not grab this one on your way)


*the next thing to do is doing all the random character missions. you can find the locations of these on youtube (YOU DO NOT NEED TO COMPLETE THE MISSIONS FROM IVAN, CHERISE, CLARENCE AND JEFF) you have met all 10 strangers at least once once you get the "No more Strangers" achievement (BUT YOU'LL NEED TO COMPLETE EVERY MISSION OF THEM)


*now you can start to hang out with your friends Brucie, Little Jacob and Packie. call them and complete every activity with these 3 friends at least once (thats about 30 activities) there is no Achievement for this, but you will obtain the "Dial B for bomb", "That's How We Roll!" and "Retail Therapy" achievements when you unlock their special abilities (THIS IS ALSO NEEDED FOR 100%) you may as well hang out with your two other friends (if they are still alive) and grab the "Liberty City (5)" achievement (not needed for 100%)




*now we're going to play some games and we must win a FULL game of bowling with a friend, a game of darts and a game of pool which gives you the "Pool Shark" achievement


*now you should look for a QUB3D machine (there is one at the strip club in Bohan) and play this mini game. when you beat the high score (11000) you get the "King of QUB3D" achievement


if you did everything correctly so far, you should have 95%, two more things to do

*one of the harder things to do is to complete all stunt jumps. find a list of them on youtube and start completing all 50 of them and you'll get the "Dare Devil" achievement


*now the hardest and most boring thing to do: find and eliminate all 200 pigeons. i would really recommend to use the list on youtube from Roosterteeth. killing these pigeons is time wasting and boring and will often get you the cops after your ass, but will give you the "Endangered Species" achievement


and then finally you will get the "Key to the City" achievement
i hope this guide helps :D

If you're serious about this achievement then you should avoid shooting any pigeons during the story phase. It's far easier to pull up a guide and make sure that you shoot them all in numerical order, plus you will know that if you can't find one it's because you haven't looked hard enough yet rather than wonder if that's the one you've already shot, and having only shot 198 or 199 after going the through the guide will infuriate you because it's going to take 5 or 6 hours to check the whole lot again.

One hint for those who don't do two run throughs:

If you only have around 2% left and have no idea what to do, then look through your contacts and go through some of the activities with your friends.


I spent about 2 hours trying to figure what to do to finish this and I went on an activity with Brucie and it unlocked and it might have glitched as well so that could be another reason.

The most important thing to keep track of is the pigeons, it's glitched and can screw you over. Everything else can be done in any order but this requires attention.

If you kill one on a mission/quest and then FAIL that mission, the worst happens - the pigeon stays dead but you do NOT get credited with the kill. This is why it's good advice to avoid killing any until the very end game; I searched all over for two I was missing and then discovered this glitch existed and had to restart.

It's a good idea to make manual saves often if you do go about killing them (by accident or deliberately) to save having to start a new save file if you fail a mission and the auto-save kicks in. It's also worthwhile checking the number remaining stays constant, you may kill one by collateral damage from a rocket launcher for example - just find one, save, then kill and see if you are prompted with a "199 remaining" message.

This site is great for finding the car thefts and strangers.
The main part of getting this is keeping track of what you've done. For example I missed one stunt jump and ended up wasting around half an hour looking for it.
If you're having trouble with the pigeons use the videos made by 007craft, they are very helpful!

Pay attention to the little things: Strangers, Friends Activities(Brucie, LJ, Packie) etc. As the jumps, Most Wanteds, Assassinations, etc they can be easily done in one sitting, the only real time consuming parts will be the pidgeons, and strangers, as strangers can take quite a while between they're "Parts" or "Story Sections".

Here's a link to the checklist site I used:
http://www.thegtaplace.com/gta4/checklist.php

Go to http://www.gta4.net/, click on interactive map where you'll find everything like the pigeons location ,Stevie's car thefts, random characters, stunt jumps and more like, weapon pick ups, health pick ups, armor pick ups,and window cleaning platforms, but those aren't really important. gta4.net is the best website to help with the achvmnt'' key to the city''.

You can take a look at this website.
http://www.gta4.net/100-percent-completion-checklist/
It has complete 100% checklist with every mission written and video guide and interactive map similar to street view with every pidgeon,random pedestrian,weapons,stunt jump. And you can even tick things to make sure you have done things and don't need to do them again.
