How do I start a 2005 ford five hundred without keys

You really need the key as it may contain a small chip to allow the engine to start because without the coded chip the engine will crank until the battery is flat or you can try and find someone to bypass the immobiliser for you but as it is part of the ecm get it wrong and replacement ecm and coding required
cheaper to get new keys cut and coded imho

1990 Cadillac Eldorado Biarritz reading shows the code e52. How do I fix?

90 Cadillac sedan deville 4.5L My car won't turn over all the power is gettin to the vehicles dash tried the trouble shooting it said it was the ECM memory reset so I changed the ECM computer and it is still doin the same thing some people say it might b the saftey neutral switch but i want to no from someone with experience opinion. I have changed the ignition module and the ECM computer recently and it still does nothing

Hi Chris, The code E52 just means that the ECM lost power or ground or that someone forgot to clear the code after hooking the battery back up. It could mean a bad computor but not very often. 2 things that come to mind is a bad ignition key or lock cylinder or a faulty neutral safety switch. Try the other ignition key first. Then with your foot on the brake pedal hold the key in the start position and move the shifter slowly from P to D. If it tries to start then the NS Switch is bad or out of adjustment. If it still won't start then you will need to troubleshoot the ignition key/PASS KEY system for an open wire in the steering column. Hope that helps. Bill

Why won't it start?

if it has a fob key battery then replace it
run the fault codes
It sounds like an immobilizer problem so a reset of the ECM using a scan tool may help

2000 saturn ls1 turns over wont start. have good fuel pressure. replaced timing chain two years age, have spark

First check fuses again. Pull them out and look. put them back in. I have fixed to many cars that corrosion kept power from getting to the part on a good fuse. You might want to do the relays also. If you still can't read the ECM. Then there are three possibilities. Your coder reader is dead, There is a bad/broken data wire, Or the ECM is dead. Could be security also. A reset. Turn the key on for ten minutes, off for thirty seconds. Try to start.

My 2003 Chrysler Sebring wont start

Check your immobilizer system. That is causing the no start condition. When you lock and unlock it with the key, you're resetting the system.

I just changed the batter in a 2002 envoy and now it wont stay running if i let off the gas please help

Try resetting the ECM, turn the ignition key to the on position "engine not running" and pull the fuse to the ECM and place it back in. Leave the keys in that position for 30 seconds and then turn it off and on again for 5 seconds and start. this will reset the ECM to default. It may stall again but let it, just start it again and let idle for 3min and go foe a test drive. This should reset the way the engine and transmission performance, and should reset the idle issue on your Envoy. Good luck and keep me posted.

try this
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.
