SOURCE: Does my Yukon have remote start?

There is NO WAY that anyone online can tell you what aftermarket equipment has been installed on your vehicle or where any of the components for such equipment would be located. It is hard enough to figure out where some of the factory installed components are located on some vehicles.

Your best bet would be to take the vehicle to an experieced auto repair technician. There is no substitute for an evaluation by someone who is familiar with the vehicle and can give it a first-hand look.

I lost my keys to my 99 Tahoe so I hot wire it it will start but won't stay running

I think because there is no key with the chip or transponder, that the security is still preventing the vehicle from staying running. Your best bet is to take the van to an automotive electrical shop. They can either bypass the security system or fit a new key that works.

Can you bypass the security system on a 2006 buick lacrosse. I don't have a passkey just a regular key and now it's saying starting disabled and the vehicle wont crant

No you can't bypass anti-theft systems as they are designed to stop exactly what you are trying to do.

Do you mean a 'valet key' that will just open the doors and glove box? Rather than a full starting key. I have never heard of a 'passkey' on a vehicle.

Contact a dealership with the vehicle VIN number and they will make you a key.that has the anti-theft chip in it. They aren't cheap but it is the only way if you have lost the original.

How to bypass alarm system lost the remote 02 ford expedition

Factory alarm is Passive. Passive Anti-Theft System. It is a transponder chip in the key and a transceiver ring around the lock cylinder. If the alarm starts go off when set and not unlocked with remote or key, inserting the programmed key into the ignition and starting will disarm the system, shut off the horn and flashing lights and allow the vehicle to start.

A question often asked, so I wrote this :>)

Want to bypass your vehicle security system?

The short answer is you can't!

All modern cars have alarms and immobilizers. There is a chip in the key and a chip in the ignition lock. If both are present, the ECM (engine control module) releases power to the ignition circuit. When you turn the key, the starter spins the engine and you get a spark. If any one of those three items are not in the chain, you get the engine to turn, but no spark. There is no way to beat the system.

The immobilizer is in place to stop exactly what you are trying to do.

Can i bypass the ignition safety lost key 01 ford escape xlt

Sorry you can't. Ford's suck because you have to have two keys to reprogram the security to the keys. Last one I had done cost about $200. Dealer only.

How do I bypass the immobiliser on mitshebushy l200

If you are looking to bypass the immobilizer permanently that is not an option. If you are installing a remote starter there are several options if you have the proper transponder key. Some company's offer bypass modules that can be programmed to the vehicle if you have 2 transponder (chip) keys. If you have only 1 key you can have it cloned and put into a device that is known in the industry as a key coffin. This device couples the signal from the coded key in the coffin into a loop or coil of wire wrapped around the key cylinder when enabled to let the car start without the transponder key in the ignition. Look for remote start bypass modules on the internet th find one for your car.Some devices can be flash programmed to your vehicle again if you have the transponder key or keys. Otherwise the only way to bypass it is with the proper factory scan tool available to dealers this is only temporary.

My 2003 Tahoe runs great, but the security light on the instrument panel stays lit when the truck is running. It does shut off when the key is off and doors are locked. What's the problem??

The security light is an indicator for a failed antitheft system. This is ALL it is for. NOTHING else. If the light is on and you are experiencing no adverse effects, you are probably alright. My guess is that the system failed, and somebody bypassed the antitheft system. (poorly) This would cause the light to be constant and the vehicle to run normally. (assuming you bought this used)

Here is a cheap way to see if the system was bypassed.
Go get a copy made of your truck key. Will cost a couple bucks. The original key has a Transponder hidden in the plastic head of the key. This transponder is a needed part of the antitheft system. The new key will NOT have this transponder. If it turns fine and starts the truck like normal, then your truck is bypassed and problem is explained and solved. If the new key turns but the truck will not remain running, then you are probably on the verge of a security failure, indicated by the security light.

Also make sure the original key is nowhere near the vehicle when you try this out. You dont want the ignition reading the signal from the original key while trialing the newly copied key

How to sTart if lost key?

Impossible to hotwire unless antitheft system is bypassed. The key holds a transponder in it that is a crucial part of the antitheft system. Without the key or bypassing the antitheft, the vehicle will not run.

My remote start will not work. The engine starts

It is probably the transponder bypass. Try this: Put a key in the ignition (do not turn on or to acc, just put it in) and hit the remote starter remote. If it starts, your transponder bypass is bad. I had this same problem. I have not been able to find just this part from Chrysler (you might).

You can purchase two types of bypasses. One actually uses a transponder key inside. The other is a computer chip that is programmed just like the transponder key. Your choice. Just do a search for "transponder bypass" and do a little research.

I used the TBKIII. Key & unit added up to $21.00. However, it only works with remote start. If I try to start with the key, it shuts down because it is picking up the key and the key in the bypass. Unit has a bypass for this, but I still have not found the correct answer to make it work. Good luck.
